Wat Si Chum

Just north of the central zone, the Wat Phra Phai Lung group of monuments stands on an area surrounded by a moat 600 m long on each side. The group of structure consists of several monuments constructed over different phases and provides an insight into the evolution of Sukhothai art and architecture.The oldest monument in the temple are 3 buildings constructed in prasad form (imitated Hindu Shikhara Vimanas) out of which only 2 stands to this day.

Located almost at the centre of the central complex, Wat Sa Si is on an island surrounded by a man made lake, known as Tra Phang Tra Kuan. It is located west of King Ramkhamhaeng Monument and north west of Wat Maha That. It includes a huge white sitting Buddha with a bell shaped chedi in the background. Also in the complex is a vihara and the ordination hall..

This lotus bud shaped chedi (stupa) is just south of the north gate (Sanluang). There is no stone inscription and nothing mush is known about the history of the temple. Wat Son Khao might have been part of the Wat Sorasak. It was restored in 1965 by the Fine Arts Department.
