The Castle Keep (Including Excavated Remains Of Forebuilding In Moat)

The Castle Keep, built in the late 11th century, stands on the site of the great Roman Claudian Temple, with its foundations still visible beneath the castle. Constructed mainly from Roman tiles and septaria, it was likely built around 1080 for William the Conqueror as a significant defensive structure. This castle was much larger and more massive than any other Norman castle in England, partly due to the need to enclose the substantial Roman foundations on the site. Originally featuring three storeys or more, it is now probably less than half its original height, yet it remains an imposing structure and an important example of medieval military architecture. Demolition began in 1693, reducing its height, and considerable restoration occurred in the mid-18th century for Charles Grey. The dome over the great staircase was added by James Deane in 1760. The site also includes the excavated remains of the forebuilding in the moat.
