According to legend, in the ninth century, King Ly Thai To was struggling to build the Hanoi Citadel, but the walls kept collapsing because of the marshy sub-soil. Bach Ma (White Horse), who was the spirit of Thang Long, appeared in the guise of a builder and told the King how to create foundations that would support the masonry. The King was grateful, and ordered the building of a pagoda dedicated to Bach Ma. A statue of the horse stands beside the altar.

The current structure was built in the 18th century, and is typical of Hanoi’s pagodas. It’s hidden away in the Old Quarter, and blends in well with its bustling streets. There is even a shop built into the walls to the left of the entrance.
