The Kho Klang Archeological Site consists of a group of ancient structures located in Ban Nong Du-Bo Khao in Tambon Ban Ruean. It is a community that belongs to the last of the ethnic Mon people who live in Lamphun today. According to a tale, handed down by word of mouth this group of old structures was built by a millionaire named In Ta who was from the ethnic Mon lineage the father of Queen Chamathewi the first ruler of Hariphunchai. The site was deserted until 1972 when it was renovated and since 1979 the Department of Religion has named it a temple for monks to reside in. This impressive group of ruins has been broken down into seven distinct buildings each with its own piece of history. These are:
Main Chedi at Wat Ko Klang, Wihan Luang (main chapel), the Mondrop, the Ubosot of Ko Klang, the Mondrop in the Water, Noen Mae Mai and Chedi Mai Tha.
