About 800 feet from the Bell Tower is the Drum Tower of Xi’an. It was built in 1380, four years before its sibling. Interestingly, no nails were used during construction. The wooden structure is 112 feet high and measures 172 feet on two sides and 124 feet on the other two. On the first level is a massive 1.5 ton drum, currently the largest in China. During the Ming and Qing dynasties, a similar drum would echo through the city on the hour. Just before sunset, it would be slowly beat 200 times. Afterwards, all city gates would close until morning. If you would like to learn more about Chinese drums, you will enjoy the museum inside of the Drum Tower. On top of the tower is a great observation platform.
