Wat Chedi Si Hong is situated outside the city wall to the south and 100m to the east of Wat Chetuphon. This temple consists of an assembly hall (vihan), a main chedi and subordinate chedis. It is worth a visit while enroute between Wat Trapang Thong Lang and Wat Chetuphon.
The highlight of this temple is its stucco relief decoration on the square platform that supports the stupa. These relief-stuccos around the base of the main chedi depict men and women in different attire with ornaments. Their hands hold vessels with flora symbolizing fertility and prosperity, decorative stuccos also include elephant and lion (simha) images. The mentioned human images may refer to Manusayanga, who according to beliefs in Sri Langka, is a divine being in the underground world. The main bell-shaped chedi has also been repaired several times. At present, the upper part of the chedi is in ruins. Its large chattra spire has broken off and remains sitting upright on the ground nearby.
