Wat Samphao Lom, or the Monastery of the Capsized Junk (1), is located off the city island in the southern area of Ayutthaya, in the Pak Kran Sub-district. The monastery is known before as Wat Tham Mai and sits on the east bank of Khlong Takhian (2).
In the north stood Wat Mai (defunct).
The monastery is still in use by the Buddhist clergy. The ordination hall is said to be the largest of Ayutthaya, measuring 45 metres long and 16 metres wide. The main Buddha image is called Luang Pho Yai, and two important other ones are Luang Pho Nak and Luang Pho Sri Aryan. The interior of the renovated Ubosot is gorgeously decorated.
Seemingly, only the outer walls are somehow the last remains of the old monastery.
Historical data about the monastery and its construction is not known.
The site is mentioned on the 1974 CE Fine Arts Department (FAD) map as Wat Samphoa Lom, on the 1993 CE FAD map as Wat Tham Mai and on the 2007 CE FAD map again as Wat Samphao Lom.
Wat Samphao Lom is in geographical coordinates: 14° 19' 52.06" N, 100° 32' 55.76" E.
