Viharn Phra Phuttha Saiyat or the Vihara of the Reclining Buddha was constructed
during the reign of King Naresuan. The new image was remodeled in 1965 after the
original got ruined by fortune hunters. The statue lies in a north-south position, with its
head in southern direction and facing the east.
In 1979 the abbot, Phra Pawanarangsi, in coordination with the Fine Arts Department
constructed a new ordination hall on the old remains, maintaining partly the ancient site,
so that the original structure remains visible.
