The Burroughs Castle is the final location in Clock Tower 3.
Located in south-east England, it was once the home of Darcy Burroughs, Natalya Burroughs, Annabel Burroughs and William Burroughs. It at least existed in the 17th century. Oddly enough, there is a secret torture site located in the catacombs of the castle. It also features a large prominent clock tower at the top.
During the game, it is shown to be buried under where the Hamilton's Mansion is currently. Dick Hamilton searched all of Europe for it, although he mentions in his notes that he found it. It is extremely unlikely an entire castle became buried under the house. Rather, the one during the game is probably part of a realm.
Clock Tower 3
During Clock Tower 3, it is raised again, apparently by some unexplained supernatural powers. It is then destroyed in the ending, apparently replaced by a field of clovers.
