"Bagayan Forest" is the three large white towers located between the Red Mountain and Yaowang Mountain of the Potala Palace in Lhasa City, Tibet. The original white tower was built in the 8th century AD and is a gateway to Lhasa City. In the 6th century, Lhasa was expanded and demolished. The current white tower was built in 1995. The former gate tower was rebuilt in the original site, which also became part of the majestic architecture of the Potala Palace, which is convenient for transportation and maintains the veins of the Shenshan Mountain. Friends who come to Lhasa must visit.
