Wat Krang, or the Monastery of the Banyan Tree, was a monastery located north of Ayutthaya at the extremity of the Pho Sam Ton fields in the Pho Sam Ton Sub-district of Bang Pahan in Ayutthaya Province.
The monastery was situated on the right bank of the Lopburi River in Ban Khai.
The temple stood near Wat Pa Fai and Wat Khao Din (Wat Wara Nayok Rangsan). Wat Krang was the most northern temple on the western bank in the Pho Sam Ton fields.
The former monastery is located today in a local brick factory. In situ is a mound with on top a commemoration pavilion (sala) next to a large Bodhi tree. The sala contains an old restored Buddha image excavated in situ. At the foot of the Bodhi tree were remnants of some sema stones. In the vicinity (a bit to the east) stands another large Bodhi tree. No other traces were found.
The former monastery was in geographical coordinates: 14° 26' 9.25" N, 100° 33' 1.61" E.
