The main prang is constructed entirely of laterite, featuring a slender and more elegant silhouette than traditional Khmer prangs. It represents the late Lopburi art style (13th-14th century), serving as a crucial prototype for early Ayutthaya-period prangs. The arches and gables still showcase exquisite stucco motifs, such as celestial beings (Thepphanam) and floral patterns. Inside the prang lies a chamber that once enshrined Buddha images and a crypt containing sacred relics and famous amulets (Phra Hu Yan). Standing tall as the central focal point of the temple, it reflects the deep faith and religious prosperity of the past.
