Lamphun is the oldest province of the North of Thailand, originally called “Nakhon Hariphunchai” or Haripunjaya. In 657, Ruesi Wasuthep gathered the Mengkhabut clansmen, who were of Mon extraction, to build the city between two rivers: the Ping and Kuang. When the settlement was finished the Ruesi or hermit asked the daughter of the Lawo City’s king, named “Chammathewi”, to rule the city.
