Situated to the east of Wat Mahathat is Wat Traphang Thong. The monastery is located on an island in the middle of a large pond. A ruined laterite Singhalese-style chedi is on the island. In front of it, a new mondop contains the Lord Buddha’s Footprint slab that was created by King Lithai in 1390 on Samanakut or Phra Bat Yai Hill. This footprint was removed to the new mondop some years ago. An annual fair to worship this sacred Lord Buddha’s Footprint takes place at the same time as the Loi Krathong Festival.
