In pictures: Zongshan Castle in China's Tibet (5/9)

This photo taken on Aug. 14, 2014 from the Zongshan Castle shows the city proper of Gyangze County in Shigaze, southwest China's Tibet Autonomous Region. Gyangze's Zongshan Castle, a mountaintop fortress, was among the main battlefields during the British invasion of Tibet between December 1903 and September 1904. About 5,000 defending soldiers stationed in the castle fought for three days against the British troops but failed to withstand the attack, which began on July 6, 1906. Unwilling to surrender, the remaining soldiers chose to jump off the Zongshan mountain. Today, the Zongshan Castle has been turned into a tourist resort. Visitors can climb up to the mountaintop and have their photographs taken infront of cannons and the castle's crumbling walls. (Xinhua/Liu Kun)
