In the eastern part of the temple complex are the remains of a Mandapa (square temple building). The remains of one large walking and one large standing Buddha Image (of the 4 original Images) are on the outside of the Mandapa. The Mandapa was build during the 14-15th century (Sukhothai period).
Wat Phra Phai Luang is like a giant historical park on its own, pleasant to walk around in. Some local people use the grounds for herding their cattle (lots of grass around).The famous Buddha Image at Wat Si Chum is very closeby, so you can visit both temples one morning or afternoon.
