16th century Cowes Castle was built as a consequence of international tensions between England,
France and the
Holy Roman Empire in the final years of the reign of King
Henry VIII. Traditionally
the Crown had left coastal defences to the local lords and communities, only taking a modest role in building and maintaining fortifications, and while France and the Empire remained in conflict with one another, maritime raids were common but an actual invasion of England seemed unlikely. Modest defences, based around simple
blockhouses and towers, existed in the south-west and along the
Sussex coast, augmented by a few more impressive works in the north of England, but in general the fortifications were very limited in scale. In 1533, Henry broke with
Pope Paul III to annul the long-standing marriage to his wife,
Catherine of Aragon, and remarry. Catherine was the aunt of
Charles V, the Holy Roman Emperor, and he took the annulment as a personal insult. This resulted in France and the Empire declaring an alliance against Henry in 1538, and the Pope encouraging the two countries to attack England. An invasion of England appeared certain. In response, Henry issued an order, called a "
device", in 1539, giving instructions for the "defence of the realm in time of invasion" and the construction of forts along the English coastline.
The Solent, a stretch of water that gave access to the ports of
Southampton and
Portsmouth, was considered vulnerable to attack. Two castles were built on the west and east sides of the
River Medina, the entrance to the principal harbour of the adjacent
Isle of Wight, and were intended to attack any enemy ships that might approach. The castles took their names from the traditional term for this location, "the Cowes". Constructed in 1539, the western fortification, which became known as West Cowes Castle, had a D-shaped
bastion at the front, a round, two-storey
keep at the rear and two low buildings on either side, all of which mounted
artillery guns. The landward side was protected by a ditch wide and a stone wall at least wide at the top. It was built from
limestone ashlar stone, which may have been recycled from the demolition of nearby
Beaulieu Abbey, a consequence of Henry's recent
dissolution of the monasteries. Settlements grew up around both castles on the Medina, but East Cowes Castle was rapidly abandoned and ultimately destroyed by
coastal erosion; as a result, today West Cowes Castle is often simply referred to as Cowes Castle. Inspections in 1547 showed that there were 17 iron and
brass artillery pieces at the fort, but that nine of these were inoperable; nonetheless it continued in use as a fortification after the original invasion scare had ended, staffed with a garrison of a captain,
porter and three
gunners during Queen
Elizabeth's reign.
17th–19th centuries Cowes Castle was used to house important visitors to the Isle of Wight and also as a prison; the captain of the castle had further responsibilities for managing the arrival of foreign vessels. When the
English Civil War broke out in 1642 between the supporters of
Charles I and Parliament, the castle was initially held for the King by its captain, Humphrey Turney. An unidentified Scottish naval captain then came ashore on 16 August and captured Turney, before landing more men and taking the castle for Parliament, who held it for the rest of the war. During the
Interregnum, the castle continued to be used as a prison. Charles I could not be housed in the castle while en route to his imprisonment by Parliament at
Carisbrooke Castle in 1647 because the facility was full, and he stayed at a local
alehouse instead. As with East Cowes Castle, coastal erosion proved a particular problem for the fortification. An inspection in 1692 reported that the walls were cracked and at risk of collapse, and the
antiquarian Francis Grose observed in 1785 that the castle was "strongly fenced with piles and planks" to prevent erosion from the sea. Cowes Castle was partially rebuilt in 1716 to modernise its accommodation. Most of the front of the keep was demolished and rebuilt with new windows, a turret for a
spiral staircase was erected, new three- and two-storey residential wings were added, and a garden was created over the landward defences. The castle remained in use during the Napoleonic Wars, and in 1825 was equipped with eleven guns. Warner had already complained, though, that the castle was "utterly useless" in military terms and a guidebook in 1824 echoed this judgement, describing Cowes as "useless as a place of defence" and ridiculing the sentries on duty there.
Lord Anglesey became the captain of Cowes Castle in 1826, by now a
sinecure rather than a regular military appointment, and spent part of each year at the castle, making further, lavish improvements to the interiors. Anglesey was also a member of the
Royal Yacht Squadron, first established in 1815, which then operated from the Gloster Hotel in Cowes. By this time yachting had become a prestigious local event; the painter
J. M. W. Turner sketched the yachts sailing off the castle when he visited in 1827. When Anglesey died in 1854 the government decommissioned the castle and leased the property initially to Anglesey's son-in-law
Lord Conyngham, and then to the Squadron in 1855. The architect
Anthony Salvin, an expert on adapting medieval buildings, was employed by the Squadron to remodel the building between 1856 and 1858. He enlarged the house, altered its profile and built a new tower, platform and a
gatehouse, along with a service wing, a
ballroom and more accommodation for the members, at a cost of around £6,000.
Prince Albert and
Edward, the Prince of Wales, visited the castle before it was formally reopened in 1858; the work received mixed reviews, one local newspaper likening the result to "a discipline establishment". After the destruction of
William IV's miniature
frigate the
Royal Adelaide in 1877, its 21 brass cannons were donated to the castle by the Prince of Wales.
20th–21st centuries 's
brass cannon at the castle in 2012 Cowes Castle was bought outright from the Crown by the Royal Yacht Squadron in 1917. Further development work was carried out on the property in the 1920s, and a ballroom in an adjacent hotel was purchased for use as an annexe for female members. The force's vessels docked in the nearby Solent, and took part in the
D-Day landings. The castle was damaged during the
German bombing raids on the island. After the war, the architect A. G. Biggs carried out substantial additions to the castle between 1962 and 1968, including remodelling the western range to provide for more female accommodation, using stone from the second
East Cowes Castle, an 18th and 19th-century stately home, which had been demolished the previous year. A prefabricated conservatory extension followed in 1988, and a new pavilion designed by Sir
Thomas Croft was added in 2000.
Archaeological excavations in the winter of 2010–11 rediscovered the remains of the old castle wall and ditch, and more than 400 artefacts were removed for storage at the Isle of Wight County Museum. Cowes Castle is a distinctive landmark in yachting and powerboat events, particularly at the start and finish of local races. It is protected under UK law as a Grade II*
Listed Building. ==Notes==
