In Guangxu 8th year of Qing Dynasty, the temple was rebuilt following the layout of Forbidden City in Beijing, thus it was also called "Little Palace in South China". The majority of the buildings have been preserved till today. During Cultural Revolution, the temple was regarded as "Four Olds", and suffered severe damages.

Three religions, Buddhism, Taoism and Confucius, co-exist in the Grand Temple of Mount Heng. Eight Temples of Taoism, Eight Temples of Buddhism and Imperial Library Tower represent the convergence of three religions. The temple enjoys great popularity among devotees. Large Buddhist festivals are held in Buddhist holidays each year. Pilgrims come not only from nearby Hunan and Guangdong, but also from Hong Kong, Macao, Southeast Asia and Japan. There was originally a statute of Mountain God in the Grand Hall, to which the past emperors all paid tribute. In early Tang Dynasty, the god was designated "Heavenly Governor Huo King". In Kaiyuan years of Tang, it was titled "Genuine Master of Mount Heng". In Song Dynasty, it was named "Heavenly Governor Zhaosheng Emperor". Today, the existent "Superior Emperor of Mount Heng" was rebuilt in 1983, for the original statute was destroyed in Cultural Revolution. There are also two "Treasury Houses" on each side of the Grand Hall. Facing from the hall, the one on the left side is designed for worship by living people, while the one on the right hosts the name boards of the deceased.
In 1990, the Chinese National Post Bureau issued a series of Mount Heng stamps , comprising 4 pieces. The first one, "Grand Temple", depicted this temple.
