The Church of Immaculada Concepcion in Baclayon is considered to be one of the oldest in the Philippines. Construction began in 1717 where some 200 native forced laborers (obras pias) cut and dragged coral blocks from the sea, using only bamboos in moving and lifting the stones in position.
Baclayon Church is a Roman Catholic Church in the municipality of Baclayon, Bohol, Philippines within the jurisdiction of the Roman Catholic Diocese of Tagbilaran. Baclayon was founded by the Jesuit priest Juan de Torres and Gabriel Sánchez in 1596, and became the oldest Christian settlement in Bohol, although in the 19th century, the Augustinian Recollects added a modern facade and a number of stone buildings that now surround the church. It was elevated as a parish in 1717 and the present coral stone church was completed in 1727. The Augustinian Recollects succeeded the Jesuits in 1768 and heavily renovated the church since then.
