The Norbulingka is the "world's highest, largest and best-preserved ancient artificial horticultural garden"., which also blends gardening with architecture and sculpture arts from several Tibetan ethnic groups; 30,000 cultural relics of ancient Tibetan history are preserved here. The complex is demarcated under five distinct sections. A cluster of buildings to the left of the entrance gate is the Kelsang Phodang (The full name of this palace is "bskal bzang bde skyid pho brang"), named after the 7th Dalai Lama, Kelsang Gyatso (1708–1757). It is a three-storied palace with chambers for the worship of Buddha, bedrooms, reading rooms and shelters at the centre. The Khamsum Zilnon, a two-storied pavilion, is opposite the entry gate. The 8th Dalai Lama, Jamphel Gyatso (1758–1804) substantially enlarged the palace by adding three temples and the perimeter walls on the south east sector and the park also came to life with plantation of fruit trees and evergreens brought from various parts of Tibet. The garden was well developed with a large retinue of gardeners. To the northwest of Kelsang Phodrong is the Tsokyil Phodrong, which is a pavilion in the midst of a lake and the Chensil Phodrong. On the west side of Norbulingka is the Golden Phodron, built by a benefactor in 1922, and a cluster of buildings which were built during the 13th Dalai Lama's time. The 13th Dalai Lama was responsible for architectural modifications, including the large red doors to the palace; he also improved the Chensel Lingkha garden to the northwest. To the north of Tsokyil Phodrong is the Takten Migyur Phodrong which was built in 1954 by 14th Dalai Lama and is the most elegant palace in the complex, a fusion of a temple and villa. The new summer palace, which faces south, was built with Central Government funds, and completed in 1956.
