Netley Castle has been described as a certain Artillery Fort.

There are masonry ruins/remnants remains.

This site is a scheduled monument protected by law.
This is a Grade 2* listed building protected by law*.


One of the Solent forts built in 1542 by Sir William Paulet at the request of Henry VIII. A single storeyed oblong structure with archways on the seaward side and strong battlemented parapet, the battlements curving convexly on their outward face. The fort was garrisoned until 1627 when it became a private residence. c1840 the fort substantially remained, with little enlargement. c1840-60, an upper storey was added, and in 1885-90 the building was transformed and greatly enlarged, with the addition of a third storey and a new wing on the SE side rising to three storeys (Pevsner; VCH).
Archaeological observations made during refurbishment works to convert the building into apartments proved the assessments of Colvin and others to be largely correct, except with respect to two significant features of the forts original form; there is no evidence of a moat, and the keep and northern platform enclosed open spaces at ground floor level probably roofed by wall fast timber structures.
Although estimates of the fort's construction date vary, it was functioning by at least 25th March 1545, when the records for payments to the garrison begin. The fort was one of a group of three around the Solent, with Southsea and St. Andrew's Point. It was maintained and garrisoned until at least 1626-7 when it was surveyed by Dutch engineers, and possibly as late as 1642 when it was reported as disabled. It was later repaired, in 1650, under the Commonwealth, in anticipation of royalist support for Charles II, but with the re-establishment of the monarchy the fort became redundant and its design obsolete.
The fort's ruinous fabric presented an ideal canvas for 19th century Romantic artists and Gothic architects. Early 18th century estate surveys indicate a gabled roof over the keep whilst the 1838 Tithes survey shows the presence of a tower at the south end by that time. Continuous redesign and refurbishment took place after the fort became a residence in the early 19th century. In 1936 the castle was sold and purchased for conversion into a convalescent home. It was converted to apartments in 2001 (M. Heaton archaeological watching brief).
A Solent fort built in 1542 and garrisoned until 1627. It then became private house. It was heightened in 1857 and an asymmetrical Gothic tower was built 1885-90. The 19th century additions added two more floors to the original single-storeyed Henry VIII building (Scheduled Monument Notification).
The Henrician artillery castle consisted of a single-storey rectangular tower (19.5m wide by 14m deep) flanked by gun platforms on either side. There were four wide embrasures facing the sea on the roof of the main building. It was built by Lord St John for Henry VIII (Harrington). (PastScape)

A royal pardon and licence to crenellate was granted in 1547 Sept 20 (Click on the date for details of this licence.).


Solent fort, said to be built in 1542 by Henry VIll out of the Abbey materials. However, the licence granted in 1547, by Edward VI to William Paulett, pardoning his building of a fortilicium at Letley, is clearly for this building. This 'pardon' (this should not be read, in any way, as a transgression by Paulett) granted considerable lands to fund the fort and a garrison of 9 men.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
