Wat Chai Watthanaram or the “Monastery of the Victorious and Prosperous Temple”
as Richard Cushman translate it, is a restored ruin situated off the city island in the
western area in Ban Pom sub-district. The large monastery is located on the west bank
of the present Chao Phraya River in front of the Siriyalai Palace, which is situated
directly across the river. The primary access to Wat Chai Watthanaram was from the
river, as the waterways were the most important means of transport in that era.
