Wat Lot Chong is an active temple located off the city island in the western area of Ayutthaya in the Ban Pom Sub-district. Khlong Klaep (1), with its mouth at the Chao Phraya River, ran south of it. In the northeast stood Wat Racha Phli (defunct), and in the south, Wat Chai Watthanaram (restored ruin).
In situ, we find an ordination hall, an open-sided vihara with seating Buddha statues and other monastic structures. The ubosot was built in the early Ayutthaya style (1351-1488 CE), but its construction dates from the Rattanakosin period (post-1851 CE). The hall has two elevated porches, with each two entries and four columns supporting the porch roof. The roof of the building is three-tiered, while the longest walls have five windows each. The ordination hall is surrounded by eight "bai sema" or boundary stones, placed in the cardinal and inter-cardinal directions and protected from the elements by small open-sided structures. The boundary stones are double, indicating former royal patronage (2). The complex is surrounded by an inner wall demarcating the sacred area.
Wat Lot Chong is named after a Thai sweet produced in earlier times in the vicinity of this temple by the locals. The refreshing sweet is made of green tapioca noodles, coconut milk, sweet syrup, and water.
Historical data about the monastery and its construction are unknown.
Based on the Temple Registration System of the National Office of Buddhism, Wat Khanon was established in 1657 CE in the late Ayutthaya period and received its Wisung Kham Sima in 1667 CE.
The 'Description of Ayutthaya', a document probably compiled early in the Bangkok era from the memories of people who had lived in Ayutthaya before 1767 CE, mentioned that in the Ayutthaya era at the village beside Wat Lot Chong, Patani Khaek weaved silk cloth, cotton cloth, and pha muang for sale in plain and in flower patterns. Merchants brought the fabric from the Khaek of Wat Lot Chong to sell at shops in the Betel Bag or Green-Cloth Market. [1]
Near Wat Lot Chong was one of the former four western ferries across the old Lopburi River - at present, the Chao Phraya River (3) - linking the monastery with the Rear Palace Landing (Tha Phra Racha Wang Lang).
The site is indicated on a 19th-century map but not on Phraya Boran Ratchathanin's map drafted in 1926 CE. On the oldest map, we find the presence of a chedi.
The site is in geographical coordinates: 14° 20' 51.81" N, 100° 32' 25.13" E.
