Arriving in the 16th century, the Portuguese were the first European settlers in Ayuthaya. Several of their skeletal remains are on view at this excavated burial site. More than 200 Portuguese and Christian converts were interred here. Behind the burial ground is the foundation of the 1540 San Petro Church, the first church built in Thailand.
Out the back, note the Thai-style spirit house with figures of St Joseph and St Paul.
