It was also known as the True Relic Pagoda. It is said that it was originally called Asoka Pagoda. It was constructed from wood and was damaged and rebuilt a number of times. During the rule of Emperor Longqing (reigned 1567–1572) of the Ming dynasty, the four-story wooden pagoda collapsed. Construction of a new thirteen-story, octagonal, brick pagoda with a height of 47 m was completed in 1609. The pagoda collapsed in 1981 and three years later the underground palace was discovered.
The present pagoda is a replica of the original structure while maintaining access to the underground palace. The palace is 21.1 m long and occupies 31.8 sq m. There are stairs leading down to a platform, followed by a corridor, front chamber, a central chamber, and a rear chamber. Beneath the north wall of the rear chamber, there is a secret niche where the Buddha’s finger bone relic was kept.
Other treasures that were unearthed include a gold alms bowl, a gilt-silver bowl, a silver robe embroidered with gold thread, a gilt-silver incense burner, a silver oil lamp, a gilt-silver statuette of Bodhisattva Holding a Relic, amber figurines of lions, a set of eight nested reliquaries, and another set of five nested reliquaries, as well as 600 other priceless treasures.
