The Reclining Buddha Vihara is situated to the north of the Great Vihara, showcasing the remnants of its foundation and fragmented walls. It once housed a reclining Buddha image crafted from brick and stucco, which has significantly deteriorated over time. The architecture exhibits the late Ayutthaya style, with possible renovations during the reign of King Narai. Positioned in a serene area, the Vihara is separated from the principal ceremonial structures within the inner grounds. This location exemplifies the age-old custom of establishing dedicated sanctuaries for diverse Buddha postures within ancient royal temples.
