Around the 14th century, the temple was associated with the Vajrasana in India. In the 18th century the Qianlong Emperor of the Qing dynasty, following the Gorkha-Tibetan war in 1792, did not allow the Nepalese to visit this temple and it became an exclusive place of worship for the Tibetans. During the Chinese development of Lhasa, the Barkhor Square in front of the temple was encroached. During the Cultural Revolution, Red Guards attacked the Jokhang temple in 1966 and for a decade there was no worship. Renovation of the Jokhang took place from 1972 to 1980. In 2000, the Jokhang became a UNESCO World Heritage Site as an extension of the Potala Palace (a World Heritage Site since 1994). Many Nepalese artists have worked on the temple's design and construction.
