Hang Nga Villa, usually called "Crazy House", was designed and built as a personal project by architect Dang Viet Nga. Its original name means "Moon Villa" as the designer and architect, Ms Dang Viet Nga, wanted to bring people closer to nature. This is why when exploring through the halls and corridors, you feel like you are inside an artery or intestine. Watch out or you might just run into a giant spider web! The house is constructed with these naturalistic themes, interpreted via concrete twists and turns. Tigers, giraffes and kangaroos made of concrete decorate the gardens, adding to the surreal environment.
