Existing cultural and historical vestiges in Yen Tu are hundreds of stupas;dozens of pagoda foundations under the Tran and Le dynasties beneath restoredpagodas; thousands of ancient objects such as statues, bells, steles, tiles,bricks, porcelain and crockery... with unique and creative motifs, patterns andarchitecture.
The Truc Lam Zen Buddhist sect gathers full of the spirit of Buddhism, butstill contains the unique features of Vietnam.
