Lingguang Temple is one of the most important existing temples in the Eight Great Places. It was first built during the Dali period of the Tang Dynasty (766-779) and was initially called "Longquan Temple". It was renamed "Jueshan Temple" during the Shizong period of the Jin Dynasty (1162). In the Xuande period of the Ming Dynasty (1428), the old name of Longquan Temple was restored. In the Zhengtong period of the Ming Dynasty (1436-1449), the temple was expanded and renamed "Lingguang Temple" after expansion.

The Hall of the Mountain Gate of Lingguang Temple faces southeast and is dedicated to the bronze and gold statue of Sakyamuni Buddha, which weighs 3,300 kg and was a gift from the King Monk of Thailand. Originally, there were five halls in Lingguang Temple, but now only three courtyards remain. They are "Great Compassion Courtyard", "Fish Pond Courtyard" and "Pagoda Courtyard". In the Great Compassion Courtyard, the south has Guanyin Hall, the north has Buddha Hall, the east and west have 14 supporting rooms. Southwest of the courtyard is a goldfish pond, which was built during the Qianlong period in the Qing Dynasty, expanded during the Xianfeng period. It was originally a pond where fish are released. By the pool, there is a pagoda base of the Liao Dynasty "immortal pagoda", also known as the "portrait of a thousand Buddha pagoda ". This pagoda was destroyed in 1900 by the the Eight-Power Allied Forces. Later, the monks in the temple found the stone letter for the relic of Buddha Sakyamuni's spiritual tooth when cleaning the old pagoda base. Walking northward via a corridor is the original Woyou Courtyard, Jushi Courtyard and Abbot's Courtyard. At present, there is a Buddha's Tooth Relic Pagoda in the Abbot's Courtyard. It was built in 1958-1964 and measures 51 meters in height with 7 stories. The relic pavilion on the second floor of the pagoda is dedicated to a Buddha's tooth of Sakyamuni in a Golden Seven Treasure Pagoda. According to the records, it was brought back from Kingdom of Khotan when the monk Fa Xian traveled west to pursue Dharma. It was first enshrined in Jiankang, the capital of the Southern Qi Dynasty. During the Sui Dynasty, it was enshrined in Daxing, which is today's Xi'an. At the end of the Tang Dynasty, it was sent to Nanjing in Liao, which is today's Beijing. In 2000, the Chinese Buddhist Association built a new Jade Buddha Hall and a screen wall of the Prajna Paramita Sutra in the handwriting of the late Buddhist Association President Zhao Puchu. Because there are only two Buddha's tooth relics left in the world, Lingguang Temple has become a place of worship for Buddhist monks all over the world.
