Opposite Wat Phra Mahathat and built in 1424, this wat is splendidly restored. The towering monuments (both rounded Khmer-style prangs and Sukhothai-style pointed chedis) have even retained some of their original stucco. King Borom Rachathirat II built the temple to honor his two brothers, who killed each other in a duel for the throne, leaving him king. In the two crypts (visitable, but not recommended for those with fear of heights, confined spaces or bats), excavators found bronze Buddha images and votive tablets, as well as golden objects and jewelry, many of which are displayed in the Chao Sam Phraya National Museum
