The Drum Tower lying on the western side of the People's Square in Nanjing City was first built in 1382 in the Ming Dynasty. Afterward, it was destroyed and rebuilt for several times. The existing structure was built at the end of the Qing Dynasty. The elevated stand of brick on which Drum Tower is rested is the original one of the Ming Dynasty. It is 8.9 meters high, 44.4 meters from east to west, and 22.6 meters from south to north. In the middle are three cylinder-shaped passageways from east to west for people to pass through.
