Potala Palace
Lhasa has many sites of historic interest, including the Potala Palace, Jokhang Temple, Sera Monastery and Norbulingka. The Potala Palace, Jokhang Temple and the Norbulingka are UNESCO world heritage sites. However, many important sites were damaged or destroyed mostly, but not solely, during China's Cultural Revolution of the 1960s. Many have been restored since the 1980s.
