Tam Thanh Pagoda

Tam Thanh Pagoda is a historic Buddhist pagoda located inside Tam Thanh Cave in Tam Thanh Ward, Lang Son City, Lang Son Province. Set within a large natural limestone cave, it is one of the most famous cave pagodas in northern Vietnam. The site is notable for its natural stalactites and stalagmites, 16th-18th century stone inscriptions and poems, and the Tam Giao statue representing Buddhism, Taoism and Confucianism.

Visitors can expect a cave temple experience inside a spacious limestone cavern accessed by stone steps. Inside are Buddhist altars and statues, natural rock formations with colorful lighting, historic stone steles and poems carved on the cave walls, and a tranquil worship area. The cave has multiple chambers to explore and offers views of the surrounding karst landscape and Lang Son City from the entrance area.

Tam Thanh Cave has been a cultural and religious site since the Le Dynasty. The pagoda was established in the 17th century and the cave preserves stone steles and poems carved by scholars and officials, including Ngo Thi Si (1726-1780) who served as garrison commander of Lang Son and composed well-known verses praising the cave's scenery. The site is recognized as a National Historical and Cultural Relic.

The pagoda is an important Buddhist pilgrimage site and a rare example of Tam Giao worship, honoring Buddhism, Confucianism and Taoism together in one statue. It serves as a center for prayer and festivals, especially during Lunar New Year, and reflects the spiritual traditions and literary heritage of the Lang Son region.
