The Portuguese Settlement in Ayutthaya was built to spread Christian ideals and to be the community center. Presently, there are still remains of ruins of the San Petro Church, known as St. Dominic's Church in the Ayutthaya period. It was the first Dominican church built in Thailand in 1540, located almost in the center of the Portuguese settlement. The area is about 2,400 square meters, along the east to west facing the Chao Phraya River. The museum is divided into three sections; the front is the Dominican Catholic cemetery. The central section is used for religious ceremonies and as a cemetery for priests. The back and the sides are for residence. Important antiquities are excavated, namely, human skeletons, tobacco pipes, coins, pottery, gem bracelets and items used in religious rituals such as crosses, coins of religious icons and rosary beads. There are over 254 human skeletons, orderly buried on the inside and outside the building. From the division line of the skeletons, the cemetery can be divided into three sections. The innermost in the center of the building is the base of the church. The skeletons inside may be a priest’s.
