The gable of Wat Phutthasaiyaram is distinguished by its low-relief stucco work by local artisans. The uppermost section depicts the five ascetics (Panchavaggiya) listening to the Buddha's teachings. Below this is an image of the reclining Buddha, reflecting the temple's name. It is adorned with finials in the style of a Naga (serpent), a characteristic of northeastern Thai art, reflecting simple yet historically significant local faith.
