Introduction to the North Tower of Xuankong Temple: The North Tower of Xuankong Temple is a three-story pavilion-style building. From bottom to top, there are the Four Buddha Hall, the Three Holy Temples, and the Three Religion Hall. Climbing to the top of the North Tower, you can see the main peak of Mount Heng towering opposite, and the Hengshan Reservoir to the south, as clear as a mirror, which is spectacular. The steep North Tower is the best place for sightseeing and photography in the temple.
