When my wife and I visited Ayutthaya Historical Park last year, we ended the day at a restaurant called Ruean Kanya to try out the famous giant river prawns. While sitting along the Chao Praya River, I noticed a building on the other side which I googled later and found out was a church named St. Joseph Church. This lovely little church, bright yellow in color, is the oldest Catholic church in Thailand. It was built in 1666 following a request of the Vietnamese missionaries headed by French Bishop Lambert de la Motte.

During the Burmese attack on Ayutthaya in 1767, the church was destroyed. Between 1831 and 1847, the church was restored in a more Rococo style. The church is located inside the Catholic school.

How getting there: When we arrived at Ayutthaya Historical Park, we hired a tuk-tuk. Some people rent bicycles or scooters. If you do so, go west and cross the Chao Phraya river on the 3263 road bridge. Then make a left to the south and pass by the Wat Chaiwatthanaram. Go on the road till you reach the 3469. Make a left again and drive a few hundred meters and you will see signs for the church on the left.
