In the "Testimony of the king from Wat Pradu Songtham", eight sacred places are listed outside the city of Ayutthaya, the glory of the capital since olden times. One of these eight places is Wat Khun In Pramun, which features a reclining Buddha of 50 meters long, considered the largest in Thailand. The Buddha image is called "Phra Sri Mueang Thong” and has a similar appearance and size to the Phra Non Jak Sri in Sing Buri Province. It is assumed to have been built in the same period. The style of the reclining Buddha is a Sukhothai Buddha statue, which is similar to the Jak Sri reclining Buddha, but the base of the image is lower. The Buddha image is handmade and slender, while the face is more beautiful.
