Following the collapse of the medieval church, the present building was constructed, funded by a grant from the
Commission for Building Fifty New Churches, to the designs of Nicholas Hawksmoor, one of the commission's two surveyors. The first church to be built by the commissioners, it was begun in 1712 and basic construction was completed in 1714; it was not, however, consecrated until 1718. The church is rectangular in plan with a flat ceiling and a small apse serving as a chancel. The east front, towards the street, has a portico in the Tuscan order, with a central arch cutting through the entablature and pediment—a motif used in
Wren's "Great Model" for
St Paul's Cathedral. Hawksmoor planned a west tower, in the position of the existing one, which had survived the collapse. However the commission was reluctant to fund it, and the medieval tower was retained. In 1730
John James refaced it, and added a spire. Hawksmoor's design, published in an engraving in 1714, had an octagonal lantern at the top, a motif he was later to use at
St George in the East.
Organs The present organ was installed in 2001, having been relocated from the Lower Chapel at
Eton College, with some minor changes. It is an 1891
Lewis & Co instrument, with modifications in 1927 by
A. Hunter & Son and 1970 by
Harrison & Harrison. Additionally, there is a small, six-stop moveable organ located in the north aisle, by W & A Boggis of
Diss from c 1960, with a later restoration by
Mander Organs.
Tallis organ The previous organ had a long history. It dated from the 16th century (when St Alfege was recorded as having a pair of organs). The
National Pipe Organ Register does not record its present whereabouts. However, a three manual drawstop
console is on display at the West End of the South aisle. This may incorporate keys from the time of the composer
Thomas Tallis, It was further restored and rebuilt in 1875 by the organ-builder Joseph Robson and
Benjamin Flight, modified by Lewis & Co in 1910 and rebuilt by R. Spurden Rutt & Co in 1934. By this point it had grown to 47 stops. It survived the bomb damage of 1941 and was rebuilt, again by R Spurden Rutt, in 1953, with 55 stops. The church is currently used to celebrate "Founder's Day" of
Addey and Stanhope School and
The John Roan School.
Churchyards The church had two churchyards, which were closed to burials in 1853. In 1889 they were transferred to the
Greenwich District Board of Works. The later of the two churchyards was laid out as a garden and recreation ground by the landscape gardener
Fanny Wilkinson, and opened in 1889. It was renamed St Alfege Park. Wilkinson planted 500 trees. In 2015 a fund-raising
cream tea garden party for
Christian Aid, held in the churchyard after the Sunday
sermon, was stormed by armed police. An attendee said that the vicar's wife was "almost knocked over by a policeman with a huge
machine gun”, but "people just carried on drinking their tea" in a display of typical British fortitude even though "all these armed police bursting in was like the film
Hot Fuzz”. The police proceeded to the adjacent St Alfege Park, where a man was arrested and a firearm found. ==Notables buried here==
