Built in 1845, the four-story Hotel Chateau Dupre building has operated as a hotel since the early 1990s.

Guests, generally vacationers with romantic intent, enter the lobby past a mural of a courtyard and pool, and through a cast-iron gate. The lobby's window provides a view of lively Decatur St.
