Wat Sakei is an unrestored ruin located off the city island in the northeastern area in Ban Ko sub-district. The ruin of the monastery is located on the confluence of the (new) Lopburi River and the (new) Pa Sak River, opposite Wat Chong Lom island and east of Wat Tong Pu. It is presently located on the premises of Wat Tong Pu school.
In situ remains only some brickwork, probably from the old ordination hall, enveloped in a tree and some broken parts of Buddha statues.
The site is not indicated on Phraya Boran Rachathanin's map drafted in 1926.
Historical data about the monastery and its construction are unknown.
