There is no record found as to when Wat Ko Mamuong Khiow was constructed, its name given by local people on account of a large mango tree growing on the site. Excavation by the Fine Arts Department took place between 2003 and 2004. On the site are the bases of a viharn and another rectangular building enclosed by a boundary wall, all in brick. Glazed ceramics from northern kilns and Chinese porcelain from the Ming Dynasty have been found on this site dating it 16th/17th century.
