Wat Yai Suwannaram was built in the Ayutthaya period and underwent restoration in the reign of King Rama V the Great. The temple, featuring a windowless main shrine hall, houses magnificent 300-year-old murals of mythical angels. Its Sala Kanprian (multi-purpose hall), which was once located in Ayutthaya's Grand Palace, was entirely built of teakwood and decorated with fine woodwork especially at the door panels. There is also a preaching throne with magnificently elaborated Bangkok style woodcarvings and gold gilt works.
