The Daying Beacon Tower, commonly known as the "Giant Tower" or "Giant Ancient Tower", is located in the Guihe Forest Park. This place used to be a military camp, and the nearby Daying Village was named after it. According to the records of relevant local chronicles, this beacon tower was supposedly built in the mid-and late Ming Dynasty. Due to its large scale and priority, the tower, together with other fortresses such as the Juyongguan, Badaling, Chadao, Yanqing, and Yongning constitutes a deep defense system for the north of the Great Wall in the Ming Dynasty. If you ride here, you can feel the vicissitudes of the Daying Beacon Tower. You can also overlook the Yongning Pavilion of the Beijing Expo Park.
