Lhasa is often referred to as the ‘Forbidden City’ due to its historical and cultural significance. The term ‘Forbidden City’ originally referred to the imperial palace in Beijing, but it has been used metaphorically to describe Lhasa because of its restricted access in the past.
During the time of the Tibetan Empire and later under the rule of the Dalai Lamas, Lhasa was considered a sacred city. Access to the city was highly restricted, especially to foreigners. The Potala Palace, which was the winter residence of the Dalai Lama, was a central part of this restriction. The palace and the city were considered off-limits to outsiders, which contributed to the mystique and the name ‘Forbidden City.’
Additionally, the geographical isolation of Lhasa, surrounded by mountains, made it difficult for people to enter. This natural barrier further reinforced the idea of Lhasa being a forbidden or inaccessible place.
In summary, Lhasa is called the ‘Forbidden City’ because of its historical restrictions on access, its sacred status, and its geographical isolation, which together created an aura of mystery and exclusivity around the city.
