Wat Tum was established during the Ayutthaya era as a location for military ceremonies. The temple has undergone continuous restoration and was elevated to the status of a royal monastery during the reign of King Rama IV. Both King Chulalongkorn and King Vajiravudh visited to perform royal merit-making ceremonies and presented monk's robes several times. Notably, during King Vajiravudh’s reign, there was a ceremony to inscribe sacred symbols and characters on Garuda flags to be bestowed as victory flags to soldiers during World War I. Wat Tum is an ancient temple, predating the establishment of Ayutthaya as the capital. It once fell into disuse but has since been restored. Inside Wat Tum, there are several points of interest, including the statue of Luang Por Thongsuk Sumpree, commonly referred to by locals as Luang Por Suk. This bronze Buddha image features a ceremonial attire and is in the Maravijaya posture. Remarkably, the statue's head, specifically at the northern part of its forehead, can be opened, revealing that the hair crown is removable. Inside the head, there is a wide basin that descends nearly to the neck area, constantly flowing with clear, cool, pure water that seeps out like sweat. This water is safe for consumption and does not dry up or disappear.
