The main highlights of Wat Si Sawai are the three prangs that feature a Lopburi architectural style, adjacent to an ordination hall made of laterite. Historians have founded numerous archaeological evidence in the area, such as statues of Hindu gods, which makes them believe it was first built as a Hindu religious structure and then later turned into a Buddhist temple. This is part of the Sukhothai Historical Park.
