Stone Inscription No. 2, known as the Wat Si Chum Inscription, was
found in a recess in the mandapa wall of
this temple. Regarded as historical

inscription deals with the founding of the
Sukhothai dynasty. Moreover, drawings
on the ceiling of the mandapa tell stories
of the former incarnations of Lord

Sukhothai alphabet for each picture. Some
of these pictures were drawn in the style of Sri Lankan art.
