Also known as the “Crazy House,” this Gaudi-inspired attraction in Dalat, Vietnam features ladders, tunnels, and hollowed-out rooms within its concrete-treehouse structure, according to the New York Times. Also an actual guesthouse, visitors can go on a guided tour of the building and may even get to chat with the “eccentric” owner/proprietor and chief architect, Ms. Dang Viet Nga.
