The Hamilton House is a location in Clock Tower 3, presumably somewhere located in England. Alyssa Hamilton resides here along with her mother Nancy Hamilton. It also serves as a residence for lodgers.
Clock Tower 3
Alyssa finds the Sacred Bottle and learns how to use Holy Water.
The house almost acts as a "hub world" for the first half of the game, as Alyssa revisits it often.
The entire house is destroyed when Burroughs Castle emerges.
