With some 2000 religious sites - 1600 Buddhist temples and 400 Shinto shrines, as well as palaces, gardens and architecture, Kyoto is one of the best preserved and most culturally distinguished cities in Japan. Among the most famous temples are Kiyomizu-dera, a magnificent wooden temple supported by pillars off the slope of a mountain; Kinkaku-ji, the Temple of the Golden Pavilion; Ginkaku-ji, the Temple of the Silver Pavilion; and Ryoan-ji, famous for its rock garden. The Heian Jingu is a Shinto shrine, built in 1895, celebrating the Imperial family and commemorating the first and last emperors to reside in Kyoto. Three special sites have connections to the imperial family: the Kyoto Gyoen area including the Kyoto Imperial Palace and Sento Imperial Palace, homes of the Emperors of Japan for many centuries; Katsura Imperial Villa, one of the nation's finest architectural treasures; and Shugaku-in Imperial Villa, one of its best Japanese gardens. The 'Historic Monuments of Ancient Kyoto' are listed by the UNESCO as a World Heritage Site. These include the Kamo Shrines (Kami and Shimo), Kyo-o-Gokokuji (To-ji), Kiyomizu-dera, Daigo-ji, Ninna-ji, Saiho-ji (Kokedera), Tenryu-ji, Rokuon-ji (Kinkaku-ji), Jisho-ji (Ginkaku-ji), Ryoan-ji, Hongan-ji, Kozan-ji and the Nijo Castle, primarily built by the Tokugawa shoguns. Other sites outside the city are also on the list.
