The Baisikou Twin Tower is located in Baisikou of Helan Mountain, 45 kilometers northwest of Yinchuan City in the Ningxia Hui Autonomous Region.

The Baisikou Twin Tower is the only brick tower with a double-eaved roof in Ningxia. Built on the south slope and running through Baisikou path, the two facing towers are 100 meters from east to west.

The east tower is octagonal in shape, with each side measuring about 2.5 meters. The tower has 13 stories and is 45 meters high. Except the first floor, which is tall, the rest floors decrease in height gradually. Two beast-headed figures are embossed on each side of the tower under the eaves of each layer. To the south of the tower gate is a 2-meter-by-50-centimeter path leading inside. The rooms are round with floors separated by thick, hollow, wooden structures. The west tower has 14 stories and is similar in shape to the east tower. Except for the first floor, each of the eight sides of each layer has a niche carved in the middle of the outer wall containing a standing Buddha statue. Both sides of each niche are decorated with beast-headed embossments with a pearl in the mouth.

The Buddhist temple originally built between the two towers has been destroyed. Although there is no record of when the twin tower was erected, the remaining cultural relics indicate that it was probably built around the Western Xia Dynasty (1038-1227).
