The principal Buddha image in the ubosot of Wat Prayun Wongsahwaht was cast 1828 AD, i.e. the same year as the ubosot was built, and is covered with gold that was imported from Japan, and considered to be a work of high quality. Unlike the dull walls of the temple's wihaan (fig.), the interior walls and pillars of the ubosot feature colourful murals.
