Tangya Tusi fortress ruins, in the Xianfeng county of Central China's Hubei province, opens to public on June 11, 2016 – the Chinese Cultural Heritage Day.

The fortress was one of three Tusi sites added to UNESCO's World Heritage List last year. Built in the early Yuan Dynasty (1271 - 1368), it covers more than 100 hectares, which is about the size of 140 football fields.

The Tusi system was a political regime adopted by feudal Chinese emperors to govern ethnic minority regions.
