The Japanese Tea Garden in Golden Gate Park is the type of Japanese garden known as a wet walking garden, although it has a Zen garden, or dry garden area as well, and is the oldest public Japanese garden in the United States. It was first developed as the Japanese Village at the 1894 California Midwinter International Exposition, or World's Fair. Located nearby, the Conservatory of Flowers has been a San Francisco landmark since 1878 and is the oldest surviving conservatory in the western hemisphere.
