Highlights: Yongtai Ancient City, located in Sitan Township, Jingtai County, Baiyin City, is a national cultural relics protection unit. Because the castle looks like a golden tortoise, it is also called Yongtai Turtle City. The Turtle City was built in the thirty-sixth year of Wanli in the Ming Dynasty. The entire city is oval in shape, with a half-moon-shaped city built on all sides. There is a moat around the city, which is a complete military barrier and fortification, and has an important strategic position in the Ming and Qing dynasties. The ancient city of Yongtai has experienced more than 400 years of vicissitudes since its establishment. The influence of the ancestors and grandsons of Yue Zhenbang, Yue Shenglong and Yue Zhongqi on the Turtle City has made Yongtai Turtle City famous. Movies and TV dramas such as "Beautiful Big Feet" and "Snow Flakes Gone" were filmed here.
