Wiang Kum Kam is an ancient “lost city” located on the banks of the Mae Ping River, around 5 km. southeast of Chiang Mai. It was founded in the 13th century by King Mangrai and was the royal capital prior to Chiang Mai. Wiang Kum Kam was abandoned in the 16th century due to flooding, and was only rediscovered in 1984. Wiang Kum Kam has been partly restored to its former glory and visitors can tour the ruins of ancient temples and see the carved stone tablets unearthed by archaeologists.
