Wat Pa Sak or "Temple of the Teak Forest" is isolated outside the walls of the ancient city of Chiang Saen, and the reason for its name is due to the 300 teak trees planted at the time of its founding in 1295, although only one pyramidal chide has been preserved in This temple, though worth exploring, is an architectural gem in Lanna style, perfectly combining the three artistic styles of Bagan, Haribunchai and Sukhothai, and is delicately decorated with carvings of flowers and mythical animals.
