16th–17th centuries Netley 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, with a few more impressive works in the north of England, but in general the fortifications were very limited in scale. (centre) and the two adjacent firing platforms In 1533, Henry then broke with Pope
Paul III in order 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. Netley Castle was built next to
Southampton Water between the mouths of the
Hamble and
Itchen rivers, south-west of the remains of
Netley Abbey. Netley Abbey had been recently
dissolved by Henry, and material from the site was reused to build the castle. The castle took the form of a central
keep, across with deep
embrasures along the
battlements, and a gun platform on either side; its design resembled that at nearby
Southsea. It was initially garrisoned with two soldiers, six gunners and a porter, under the command of a captain.
18th–20th centuries William Chamberlayne inherited the castle in 1826 and built a crenellated tower on the south-east end of the property the following year, inspired by a proposal by the
antiquarian Horace Walpole that the castle be made habitable. A description of the castle around this time suggested it stood "in the midst of a thicket of trees, on a little hill close to the beach" and formed "a striking object seen from the water". It became popular with artists, and
J. M. W. Turner visited and sketched the castle and its new tower, probably in 1832. George Hunt leased the castle in 1841 and it was turned into a private house under the supervision of the architect George Guillame. Hunt remained at Netley until 1857, by when the castle had an
oriel window overlooking the sea, and the battlements had been blocked in to allow the construction of a second storey to the building. George Sherriff leased the castle between 1868 and 1873, building a stone wall around the front of property. After Crichton's death in 1922 his wife remained in the house until her death in 1936, when the property and the surrounding grounds were sold at auction.
Middlesex County Council bought the castle in 1939 and converted it into a
nursing home for elderly men; it passed into the control of the
National Health Service in 1948 and continued to be used as a nursing home.
21st century Fairmist Limited, a firm of property developers, purchased Netley Castle in 2000 and converted it into nine private residential flats, at a cost of £1.7 million, during which process an
archaeological survey was made of the property. It is protected under UK law as a
Scheduled Monument and a Grade II*
listed building. The castle is now approximately across and tall, surrounded by of land. The north wing is three storeys tall, decorated in a restrained
Gothic style and has an octagonal turret on one corner. The central range is two storeys tall, with round corner turrets and battlements. The southern wing is two storeys in height, with elaborate Gothic detailing and another, larger octagonal tower. The castle features a substantial staircase, fitted with a
musical organ, and a wood-panelled
billiard room. Other buildings around the main castle include the converted boat house and a former
ice house. ==See also==
