The Bell Tower, is a stately traditional building, that marks the geographical center of the ancient capital. From this important landmark extend East, South, West and North Streets, connecting the Tower to the East, South, West and North Gates of the City Wall of the Ming Dynasty.

The wooden tower, which is the largest and best-preserved of its kind in China, is 36 meters (118 feet) high. It stands on a brick base 35.5 meters (116.4 feet) long and 8.6 meters (28.2 feet) high on each side. During the Ming Dynasty, Xian was an important military town in Northwest China, a fact that is reflected in the size and historic significance of its tower.

The tower was built in 1384 by Emperor Zhu Yuanzhang as a way to dominate the surrounding countryside and provide early warning of attack by rival rulers.

The tower has three layers of eaves but only two stories. Inside, a staircase spirals up. The grey bricks of the square base, the dark green glazed tiles on the eaves, gold-plating on the roof and gilded color painting make the tower a colorful and dramatic masterpiece of Ming-style architecture. In addition to enhancing the beauty of the building, the three layers of eaves reduce the impact of rain on the building.

On the second floor, a plaque set in the west wall records the relocation of the tower in 1582. When it was first built in 1384, it stood near the Drum Tower on the central axis of the city, and continued to mark the center of the city since Tang Dynasty and the following the Five Dynasties and the Song and Yuan Dynasties. As the city grew, however, the geographical center changed. Therefore, in 1582, the Tower was moved 1,000 meters (3,280 feet) east of the original site. Except for the base, all parts are original, and history tells us that the relocation was accomplished quickly and inexpensively, making it a truly notable achievement in the architectural history in China.
