Kingsgate Castle

Kingsgate Castle on the cliffs above Kingsgate Bay, Kent, was built for Henry Fox, 1st Baron Holland, in the 1760s. The name Kingsgate is related to a landing of Charles II on 30 June 1683 (‘gate’ referring to a cliff-gap) though other English monarchs have also used this cove, such as George II in 1748.

Unfortunately now the building is privatly owned after a conversion into 31 flats in the 1990s, some "aesthetic enhancements" and functional changes, and it's not accessable for the public.
