St Paul's Cathedral is built in a restrained
Baroque style which represents Wren's rationalisation of the traditions of English medieval cathedrals with the inspiration of
Palladio, the classical style of Inigo Jones, the baroque style of 17th century Rome, and the buildings by Mansart and others that he had seen in France. It is particularly in its plan that St Paul's reveals medieval influences. Like the great medieval cathedrals of
York and
Winchester, St Paul's is comparatively long for its width and has strongly projecting transepts. It has much emphasis on its facade, which has been designed to define rather than conceal the form of the building behind it. In plan, the towers jut beyond the width of the aisles as they do at
Wells Cathedral. Wren's uncle
Matthew Wren was the
Bishop of Ely, and, having worked for his uncle, Wren was familiar with the unique octagonal lantern tower over the crossing of
Ely Cathedral, which spans the aisles as well as the central nave, unlike the central towers and domes of most churches. Wren adapted this characteristic in designing the dome of St Paul's. In section St Paul's also maintains a medieval form, having the aisles much lower than the nave, and a defined clerestory.
Exterior The most renowned exterior feature is the dome, which rises to the cross at its summit, and dominates views of the city. The height of 365 feet is explained by Wren's interest in astronomy. Until the late 20th century, St Paul's was the tallest building on the City skyline, designed to be seen surrounded by the delicate spires of Wren's other city churches. The dome is described by Sir
Banister Fletcher as "probably the finest in Europe", by
Helen Gardner as "majestic", and by Sir
Nikolaus Pevsner as "one of the most perfect in the world". Sir
John Summerson said that Englishmen and "even some foreigners" consider it to be without equal.
Dome Wren drew inspiration from Michelangelo's dome of St Peter's Basilica and that of Mansart's Church of the Val-de-Grâce, which he had visited. Unlike those of St Peter's and Val-de-Grâce, the dome of St Paul's rises in two clearly defined storeys of masonry, which, together with a lower unadorned footing, equal a height of about 95 feet. From the time of the
Greek Cross Design it is clear that Wren favoured a continuous colonnade (
peristyle) around the drum of the dome, rather than the arrangement of alternating windows and projecting columns that Michelangelo had used and which had also been employed by Mansart. Summerson suggests that he was influenced by Bramante's "Tempietto" in the courtyard of
San Pietro in Montorio. In the finished structure, Wren creates a diversity and appearance of strength by placing niches between the columns in every fourth opening. The peristyle serves to buttress both the inner dome and the brick cone, which rises internally to support the lantern. Above the peristyle rises the second stage, surrounded by a balustraded balcony called the "Stone Gallery". This attic stage is ornamented with alternating pilasters and rectangular windows, which are set just below the cornice, creating a sense of lightness. Above this attic rises the dome, covered with lead and ribbed in accordance with the spacing of the pilasters. It is pierced by eight light wells just below the lantern, but these are barely visible. They allow light to penetrate through openings in the brick cone, which illuminates the interior apex of this shell, partly visible from within the cathedral through the ocular opening of the lower dome. The lantern, like the visible masonry of the dome, rises in stages. The most unusual characteristic of this structure is that it is of a square plan, rather than circular or octagonal. The tallest stage takes the form of a
tempietto with four columned porticos facing the cardinal points. Its lowest level is surrounded by the "Golden Gallery" and its upper level supports a small dome from which rises a cross on a golden ball. The total weight of the lantern is about 850 tons.
West front For the Renaissance architect designing the west front of a large church or cathedral, the universal problem was how to use a facade to unite the high central nave with the lower aisles in a visually harmonious whole. Since
Alberti's additions to
Santa Maria Novella in Florence, this was usually achieved by the simple expedient of linking the sides to the centre with large brackets. This is the solution that Wren saw employed by Mansart at Val-de-Grâce. Another feature employed by Mansart was a boldly projecting Classical portico with paired columns. Wren faced the additional challenge of incorporating towers into the design, as had been planned at St Peter's Basilica. At St Peter's,
Carlo Maderno had solved this problem by constructing a
narthex and stretching a huge screen facade across it, differentiated at the centre by a pediment. The towers at St Peter's were not built above the parapet. Wren's solution was to employ a Classical portico, as at Val-de-Grâce, but rising through two storeys and supported on paired columns. The remarkable feature here is that the lower story of this portico extends to the full width of the aisles, while the upper section defines the nave behind it. The gaps between the upper stage of the portico and the towers on either side are bridged by a narrow section of wall with an arch-topped window. The towers stand outside the width of the aisles but screen two chapels located immediately behind them. The lower parts of the towers continue the theme of the outer walls but are differentiated from them to create an appearance of strength. The windows of the lower story are smaller than those of the side walls and are deeply recessed, a visual indication of the thickness of the wall. The paired pilasters at each corner project boldly. Above the main
cornice, which unites the towers with the portico and the outer walls, the details are boldly scaled in order to read well from the street below and from a distance. The towers rise above the cornice from a square block plinth, which is plain apart from large oculi, that on the south being filled by the clock, while that on the north is void. The towers are composed of two complementary elements, a central cylinder rising through the tiers in a series of stacked drums, and paired
Corinthian columns at the corners, with
buttresses above them, which serve to unify the drum shape with the square plinth on which it stands. The entablature above the columns breaks forward over them to express both elements, tying them together in a single horizontal band. The cap, an ogee-shaped dome, supports a gilded finial in the form of a pineapple. The transepts each have a semi-circular entrance portico. Wren was inspired in the design by studying engravings of
Pietro da Cortona's Baroque facade of
Santa Maria della Pace in Rome. These projecting arcs echo the shape of the apse at the eastern end of the building.
Walls The building is of two storeys of ashlar masonry, above a basement, and surrounded by a balustrade above the upper cornice. The balustrade was added, against Wren's wishes, in 1718. The internal bays are marked externally by paired pilasters with Corinthian capitals at the lower level and Composite at the upper level. Where the building behind is of only one story (at the aisles of both nave and choir), the upper story of the exterior wall is a sham. It serves a dual purpose of supporting the buttresses of the vault and providing a satisfying appearance when viewed rising above buildings at the height of the 17th-century city. This appearance may still be seen from across the
River Thames. Between the pilasters on both levels are windows. Those of the lower storey have semi-circular heads and are surrounded by continuous mouldings of a Roman style, rising to decorative keystones. Beneath each window is a floral swag by Grinling Gibbons, constituting the finest stone carving on the building and some of the greatest architectural sculpture in England. A frieze with similar swags runs in a band below the cornice, tying the arches of the windows and the capitals. The upper windows are of a restrained Classical form, with pediments set on columns, but are blind and contain niches. Beneath these niches, and on the basement level, are small windows with segmental tops, the glazing of which catches the light and visually links them to the large windows of the aisles. The height from ground level to the top of the parapet is approximately 110 feet.
Railings The original iron churchyard railings surrounding the cathedral, designed by Wren, were installed in 1714 on a Portland stone base. In the 1870s, the Surveyor of the Fabric,
Francis Penrose, had the railings lowered and removed them altogther from the west forecourt, replacing them with bollards.
John George Howard bought the surplus railings and had them shipped to
Toronto, where he was the municiple syrveyor. Although the ship carrying them sank in the
St Lawrence River and had to be salvaged at Howard's expense, they have since adorned his tomb in
High Park, his former estate.
Interior Internally, St Paul's has a nave and choir in each of its three bays. The entrance from the west portico is through a square domed narthex, flanked by chapels: the Chapel of St Dunstan to the north and the Chapel of the Order of St Michael and St George to the south. The nave is in height and is separated from the aisles by an arcade of piers with attached Corinthian pilasters rising to an entablature. The bays, and therefore the vault compartments, are rectangular, but Wren roofed these spaces with saucer-shaped domes and surrounded the
clerestory windows with
lunettes. The vaults of the choir are decorated with mosaics by Sir
William Blake Richmond. The dome and the apse of the choir are all approached through wide arches with coffered vaults, which contrast with the smooth surface of the domes and punctuate the division between the main spaces. The transepts extend to the north and south of the dome and are called (in this instance) the North Choir and the South Choir. The
choir holds the stalls for the clergy, cathedral officers, and the choir, and the organ. These wooden fittings, including the pulpit and Bishop's throne, were designed in Wren's office and built by joiners. The carvings are the work of
Grinling Gibbons whom Summerson describes as having "astonishing facility", suggesting that Gibbons' aim was to reproduce popular Dutch flower painting in wood.
Jean Tijou, a French metalworker, provided various wrought iron and gilt grilles, gates, and balustrades of elaborate design, of which many pieces have now been combined into the gates near the sanctuary. The cathedral is some in length (including the portico of the Great West Door), of which is the nave and is the choir. The width of the nave is and across the transepts is . The cathedral is slightly shorter but somewhat wider than Old St Paul's.
Dome The main internal space of the cathedral is under the central dome, which extends the full width of the nave and aisles. The dome is supported on
pendentives rising between eight arches spanning the nave, choir, transepts, and aisles. The eight piers that carry them are not evenly spaced. Wren has maintained an appearance of eight equal spans by inserting segmental arches to carry galleries across the ends of the aisles and has extended the mouldings of the upper arch to appear equal to the wider arches. Above the keystones of the arches, at above the floor and wide, runs a cornice which supports the
Whispering Gallery so called because of its acoustic properties: a whisper or low murmur against its wall at any point is audible to a listener with an ear held to the wall at any other point around the gallery. It is reached by 259 steps from ground level. The dome is raised on a tall drum surrounded by pilasters and pierced with windows in groups of three, separated by eight gilded niches containing statues and repeating the pattern of the peristyle on the exterior. The dome rises above a gilded cornice at to a height of . Its painted decoration by
Sir James Thornhill shows eight scenes from the life of
St Paul set in illusionistic architecture which continues the forms of the eight niches of the drum. At the apex of the dome is an
oculus inspired by that of the
Pantheon in Rome. Through this hole can be seen the decorated inner surface of the cone, which supports the lantern. This upper space is lit by the light wells in the outer dome and openings in the brick cone. Engravings of Thornhill's paintings were published in 1720.
Apse The eastern
apse extends the width of the choir and is the full height of the main arches across the choir and nave. It is decorated with mosaics, in keeping with the choir vaults. The original reredos and high altar were destroyed by bombing in 1940. The present high altar and
baldacchino are the work of
W. Godfrey Allen and
Stephen Dykes Bower. The apse was dedicated in 1958 as the American Memorial Chapel. It was paid for entirely by donations from British people. The Roll of Honour contains the names of more than 28,000 Americans who gave their lives while on their way to, or stationed in, the United Kingdom during the Second World War. It is in front of the chapel's altar. The three windows of the apse date from 1960 and depict themes of service and sacrifice, while the insignia around the edges represent the American states and the
US armed forces. The limewood panelling incorporates a rocket—a tribute to America's
achievements in space.
Artworks, tombs and memorials St Paul's, at the time of its completion, was adorned by sculpture in stone and wood: most notably that of Grinling Gibbons, by the paintings in the dome by Thornhill, and by Jean Tijou's elaborate metalwork. It has been further enhanced by Sir William Richmond's mosaics and the fittings by Dykes Bower and Godfrey Allen. Other artworks in the cathedral include, in the south aisle,
William Holman Hunt's copy of his painting
The Light of the World, the original of which hangs in
Keble College, Oxford. The St Paul's version was completed with significant input from
Edward Robert Hughes as Hunt was now suffering from glaucoma. In the north choir aisle is a limestone sculpture of the
Madonna and Child by
Henry Moore, carved in 1943. The crypt contains more than 200 memorials and numerous burials. Christopher Wren was the first person to be interred, in 1723. On the wall above his tomb in the crypt is written in Latin:
Lector, si monumentum requiris, circumspice ("Reader, if you seek his monument, look around you"). The largest monument in the cathedral is that to the
Duke of Wellington by
Alfred Stevens. It stands on the north side of the nave and has on top a statue of Wellington astride his horse "Copenhagen". Although the equestrian figure was planned at the outset, objections to the notion of having a horse in the church prevented its installation until 1912. The horse and rider are by
John Tweed. The Duke is buried in the crypt. The tomb of
Horatio, Lord Nelson is located in the crypt, next to that of Wellington. The marble
sarcophagus which holds Nelson's remains was made for
Cardinal Wolsey but not used as the cardinal had fallen from favour. At the eastern end of the crypt is the Chapel of the
Order of the British Empire, instigated in 1917, and designed by
John Seely, Lord Mottistone. There are many other memorials commemorating the British military, including several lists of servicemen who died in action, the most recent being the
Gulf War. Also remembered are
Florence Nightingale,
J. M. W. Turner,
Arthur Sullivan,
Hubert Parry,
Samuel Johnson,
Lawrence of Arabia,
William Blake,
William Jones and Sir
Alexander Fleming as well as clergy and residents of the local parish. There are lists of the bishops and cathedral deans for the last thousand years. One of the most remarkable sculptures is that of the Dean and poet,
John Donne. Before his death, Donne posed for his own memorial statue and was depicted by
Nicholas Stone as wrapped in a burial shroud and standing on a funeral urn. The sculpture, carved around 1630, is the only one to have survived the conflagration of 1666 intact. The treasury is also in the crypt, but the cathedral has very few treasures as many have been lost and, on 22 December 1810, a major robbery took almost all of the remaining precious artefacts. Memorials thus contextualised include the statues of
Charles George Gordon, Arthur Wellesley, 1st Duke of Wellington,
Richard Southwell Bourke, 6th Earl of Mayo,
Bishop Thomas Fanshaw Middleton,
Granville Gower Loch, William Jones,
Charles Cornwallis, 1st Marquess Cornwallis,
Henry Montgomery Lawrence,
Henry Bartle Frere,
Robert Cornelius Napier, 1st Baron Napier of Magdala,
Charles James Napier,
Charles Metcalfe MacGregor,
Samuel James Browne,
Harry Smith Parkes, and the Indian Army Volunteers memorial. The trail has a printed guide that visitors may use, and the statues on the trail are identifiable by a graphic and a QR code, which leads to the relevant webpage upon scanning. The graphic is original artwork produced by graphic design artist Sonal Agarwal and represents a cluster of statues of South Asian persons, men and women, who currently serve as decorative or supportive features of the main statues.
Geometric Staircase The
Geometric Staircase, a helical cantilevered staircase rising 50 feet with 88 stone stairs, designed by Christopher Wren, was built by
William Kempster in the southwest tower of the cathedral and completed in 1710. The steps are only embedded about 150mm into the walls since they are mainly supported by the steps below. The staircase has been featured in several major films.
Clock A clock was installed in the southwest tower by Langley Bradley in 1709 but was worn out by the end of the 19th century. The present mechanism was built in 1893 by
Smith of Derby incorporating a design of escapement by
Edmund Denison Beckett similar to that used by
Edward Dent on
Big Ben's mechanism in 1895. The clock mechanism is long and is the most recent of the clocks introduced to St Paul's Cathedral over the centuries. Since 1969, the clock has been electrically wound with equipment designed and installed by Smith of Derby, relieving the clock custodian from the work of cranking up the heavy drive weights.
Great Paul The southwest tower also contains four bells, of which
Great Paul, cast in 1881 by
J. W. Taylor of
Taylor's bell foundry of
Loughborough, at was the largest bell in the
British Isles until the casting of the
Olympic Bell for the 2012 London Olympics. On 31 July 2021, during the London Festival of the Bells, Great Paul rang for the first time in two decades, being hand swung by the bell ringers.
Great Tom The clock bells include
Great Tom, which was moved from
St Stephen's Chapel at the
Palace of Westminster and has been recast several times, the last time by
Richard Phelps. It chimes the hour and is traditionally tolled on occasions of a death in the royal family, the Bishop of London, or the
Lord Mayor of London, although an exception was made at the death of the US president
James Garfield. It was last tolled for the death of
Queen Elizabeth II in 2022, ringing once every minute along with other bells across the country in honour of the 96 years of her life.
Quarter-jacks In 1717, Richard Phelps cast two more bells that were added as "quarter jacks" that ring on the quarter hour. Still in use today, the first weighs , is in diameter and is tuned to A; the second weighs , is in diameter and is tuned to E. They are sometimes known as
Ding and
Dong due to the way they sound.
Bells The northwest tower contains 13 bells: a
ring of 12 bells by John Taylor & Co of Loughborough hung for
change ringing, and the single communion bell. In January 2018, the bells were removed for refurbishment and were rehung in September that year, being rung again for the first time on
All Saints' Day. The original service or "Communion" bell dating from 1700 and known as "the Banger" is rung before 8 a.m. services. ==Education, tourism, and the arts==
