Sanjusangendo is the popular name for Rengeo-in, a temple in eastern Kyoto which is famous for its 1001 statues of Kannon, the goddess of mercy. The temple was founded in 1164 and rebuilt a century later after the original structure had been destroyed in a fire.
The temple hall is with 120 meters Japan's longest wooden structure. The name Sanjusangendo (literally "33 intervals") derives from the number of intervals between the building's support columns, a traditional method of measuring the size of a building. In the center of the main hall sits a large, wooden statue of a 1000-armed Kannon that is flanked on each side by 500 statues of human sized 1000-armed Kannon standing in ten rows. Together they make for an awesome sight.
