Hang Nga Guesthouse, Crazy House, Đà Lạt, Vietnam

Hằng Nga guesthouse (Vietnamese: Biệt thự Hằng Nga), popularly known as the “Crazy House” (Vietnamese: Ngôi nhà quái dị), is an unconventional building designed and constructed by Vietnamese architect Dang Viet Nga in Đà Lạt, Vietnam. Described as a “fairy tale house”, the building’s overall design resembles a giant tree, incorporating sculptured design elements representing natural forms such as animals, mushrooms, spider webs and caves. Its architecture, comprising complex, organic, non-rectilinear shapes, has been described as expressionist. Nga has acknowledged the inspiration of Catalan architect Antoni Gaudí in the building’s design, and visitors have variously drawn parallels between it and the works of artists such as Salvador Dalí and Walt Disney. Since its opening in 1990, the building has gained recognition for its unique architecture, being highlighted in numerous guidebooks and listed as one of the world’s ten most “bizarre” buildings in the Chinese People's Daily.
Design
Hang Nga guesthouse was originally built as a personal project by Vietnamese architect Dang Viet Nga, opening to the public in 1990. Nga, who received a PhD in architecture from the University of Moscow, has stated that her overall design was inspired by the natural environment surrounding of the city of Da Lat, along with the work of Catalan architect Antoni Gaudí.
