Miagao Church — formally the Church of Santo Tomás de Villanueva — is a UNESCO World Heritage Site about 40 kilometres southwest of Iloilo City, one of the four Philippine Baroque Churches inscribed in 1993. Built between 1787 and 1797 from locally quarried limestone, it is considered the finest example of Philippine Baroque architecture for the quality of its carved facade and the integration of local cultural imagery into the stone relief work.
The church towers double as watchtowers and the walls are up to a metre thick, designed for defence against the coastal raids that regularly struck the region. Getting there from Iloilo requires a bus or van (about 1 to 1.5 hours) along the coastal road. The church is still in active use as the parish church of Miagao town, and the plaza in front of it has a quiet provincial character entirely different from the bustle of the city.
