Sanju-no-to, a three-story pagoda, is a form of temple architecture housing relics of the Buddha and of other holy persons. This pagoda was moved here in 1914 from Tomyoji Temple in Kizugawa City, Kyoto. Built in 1457, it is the oldest building in Sankeien. After it was relocated, it served as a key influence on the layout of the remainder of the inner garden. The entire inner garden was designed specifically so that the elegant pagoda could be seen from the interiors of many of the other buildings.
