• The notice on the metal plate at Wat U Mong describes that this temple was firstly called Werukattathatamr which means the temple of the eleven clumps of bamboo. Old records state that after the founding of Chiang Mai around 1297 A.D. King Mangrai built this temple in an area of the eleven clumps of bamboo for Phra Thera Chan and Sri Lankan monks to reside. Later a tunnel [ '' U Mong '' in Thai ] was constructed by the command of Phraya Kuena and since then the Temple was called U Mong Thera Chan or Wat U Mong.
• The principal Chedi of the Temple is situated on an open mound and within a boundary wall. The Chedi has a Naga staircase built on the south side which is the only entrance to the mound. On the east of the mound can be seen the open roof of parts of the tunnel. The entrance to the tunnels is on the lower mound and the tunnel doorway faces south. The tunnel is used to reside image s of Buddha. The lower court in front of the tunnel contains pavilions, monks' residences and a stone pillar with Indian lion sculptures on the top.
