Great Wall Fort at Jiayuguan

15. Corner Tower

A fabulous legend recounts the meticulous planning involved in the construction of the pass. According to legend, when Jiayuguan was being planned, the official in charge asked the designer to estimate the exact number of bricks required and the designer gave him a number. The official questioned his judgment, asking him if that would be enough, so the designer added one brick. When Jiayuguan was finished, there was one brick left over, which was placed loose on one of the gates where it remains today.
