Wat Suthat was built in the early nineteenth century to house the huge 25-foot tall Phra Sri Sakyamuni Buddha statue, which was bought all the way from Sukhothai by boat. The Wiharn housing the Buddha image sits in a large cloister. The outer wall of the cloister is lined with more than 150 Buddha images. The statues are in various states of repair, since each is "adopted" by a patron to make merit for a departed loved one, who may in fact be interred in the base or the wall next to the Buddha. In late 2007, there was a project under way to re-gild each of the statues.
Be sure to have a look at the doors to the cloister in the middle of each of the four walls. They are painted and gilded with quite colorful scenes from the Ramakien.
