Layout of the temple was a rectangle. Viharn was home to the Phra Si Sanphet Dayan, the standing Buddha with 16 meters height. The core of the statue made of bronze covered with gold. During the second war, the Buddha was burnt for gold taking by Burmese, leaving only the bronze core. Currently the core is stored inside Phra Maha Chedi Si Sanphet Dayan at Wat Pho, Bangkok.
Behind the viharn, there are three large main chedis contained the bone of three kings. The subordinate chidis are collected other royal member bones. The survey found that the chedi vault was kept a seven-tier miniature chedi with Buddha relics inside.
