The Baclayon Church, formally the Church of Our Lady of the Immaculate Conception, is the oldest church in Bohol and one of the oldest in the Philippines, built by the Augustinians beginning in 1595. It stands in the town of Baclayon, about 7 km east of Tagbilaran along the coastal road. The church is constructed almost entirely from coral limestone blocks, giving it a texture and colour unlike brick or stone churches elsewhere.
The museum attached to the church holds religious artefacts from the Spanish colonial period — vestments, liturgical silver, old bibles — and is worth a look. The church was badly damaged in the 2013 Bohol earthquake but has been substantially restored. Sunday Mass here draws the local congregation and gives a sense of how these old buildings remain living parts of the community rather than mere monuments.
