Wat Phumin is different from the rest of the wats in Thailand. The ordination and assembly halls are put together in one building which is constructed on a cross-shaped plan.
The building has square center and has four equal projections with identical projections at cardinal points. Impressive Naga balustrades are made along the steps leading to the doors, which is the typical of the Buddhist hall of the north. This charming architecture was reproduced on One Baht Bill in brown hues during the time of World War II in the 1940's.
