Norbulingka, a National Key Cultural Relic Protection Site, is located in the western suburbs of Lhasa. Originally built in the 1740s during the reign of the Seventh Dalai Lama, it served as the summer retreat for successive Dalai Lamas. It is a typical Tibetan-style garden. After over 200 years of expansion, the garden now covers 360,000 square meters and boasts over 100 plant species. These include not only common flowers and trees in Lhasa, but also exotic plants from the southern and northern foothills of the Himalayas, as well as rare flowers transplanted from inland areas or imported from abroad. It is truly a highland botanical garden. Norbulingka means "treasure garden." Designated a People's Park, it is sometimes jokingly described as "a water tower, two rows of handicraft shops, and several palaces surrounding a zoo." Norbulingka has gates on all four sides, with the main entrance on the east. The most striking pavilion on the facade is Kangsong Silun. Originally a small Han-style wooden pavilion, it was later converted into a theater. A spacious venue was added to the east, specifically for the Dalai Lama to watch performances. Next to it is Xiabudian Lakang, a venue for religious ceremonies. Before liberation, Norbulingka was merely a "summer palace" for the Dalai Lama and a few dignitaries to relax and unwind. After liberation, it underwent renovations and a revamped look, now home to 49 species of trees, including pines and cypresses, 62 varieties of rare flowers and plants, including peonies and Chinese peonies, and 15 species of birds and animals. The park boasts beautifully maintained flower beds and lawns, exquisite pavilions and waterside terraces, a stage, and wooden tables and benches.
