Thay Pagoda

Thay Pagoda (Chua Thay) is an ancient Buddhist pagoda complex at the foot of Sai Son Mountain in Sai Son Commune, Quoc Oai District, about 30 km southwest of central Hanoi. Founded in the 11th century during the Ly Dynasty and dedicated to Zen master Tu Dao Hanh, it is noted for its historic architecture, scenic Long Chieu Lake with two curved bridges, mountain caves, and its status as a Special National Relic and center of traditional water puppetry.

Visitors can expect a tranquil complex of three parallel structures (Ha, Trung and Thuong Pagodas) set against Sai Son Mountain and fronted by Long Chieu Lake. Two historic arched bridges, Nhat Tien and Nguyet Tien, cross the lake. Inside are statues of Buddha and Zen master Tu Dao Hanh, ancient altars, and steles. Trails lead up the mountain to Cac Co Cave and viewpoints, with courtyards, gardens and water puppet stage areas to explore.

Founded in the 11th century during the reign of Ly Nhan Tong and associated with Zen master Tu Dao Hanh (1072-1116). The pagoda was built at the site of his practice and later restored during Tran and Le dynasties, preserving Ly Dynasty architectural style. It was designated a Special National Relic in 2014 for its historical and architectural value.

Dedicated to Tu Dao Hanh, revered as a Buddhist monk, healer and founder of Vietnamese water puppetry. The pagoda is a major Buddhist pilgrimage site and center for folk beliefs. Its annual festival on the 7th day of the 3rd lunar month features processions, incense offerings, and water puppet performances on Long Chieu Lake, reflecting Vietnamese Buddhist and folk traditions.
