Jiayuguan Fort (Jiayu Pass)

Jiayuguan Fort, also called Jiayu Pass, is the best-preserved Ming-dynasty fortress pass at the western end of the Great Wall, standing about 7 km northwest of the city of Jiayuguan in Gansu, China. Construction began in 1372 and the pass was built in the narrowest point of the corridor between the Qilian Mountains to the south and the Heishan range to the north, making it a natural chokepoint on the route west. The fort consists of an inner city, an outer city and a moat, with walls of rammed earth and brick that enclose a compact military settlement. Three main gate towers rise above the walls, the best known being the Guanghua Gate on the east and the Rouyuan Gate on the west, each with a multi-storey tower and a protected approach. Visitors climb the walls and the towers, walk along the parapets and look down into the courtyard, where exhibits, a small museum and displays of weapons and fortress life explain how the garrison operated. A local legend about a single spare brick left on a gate ledge is retold at the site. From the ramparts, visitors have wide views of the desert plain, the snow-topped mountains and, on clear days, the long line of the wall running into the distance. The main ticket is valid for three days and also covers the Overhanging Great Wall and the First Beacon Tower, so many visitors use it to visit all three sites in sequence. A visit to the fort itself takes two to three hours. Morning and late afternoon light is best for photographs, and in peak summer the wall is lit in the evening. Crowds are heaviest in the middle of the day, in July and August, and during national holidays, when tour groups fill the courtyard. Visitors should bring water and sun protection, and should check opening hours and prices before travelling.
