Church of Saint Blaise of Nicoya, Colonial church in Nicoya, Costa Rica.

The Church of Saint Blaise is a colonial religious building in central Nicoya with a white facade, central nave, and bell tower. The structure follows Spanish architectural design from the 1600s and occupies a raised plaza in the town center.

A first chapel of wood and thatch was begun between 1522 and 1544 and burned down. The 1644 church of stone and tile was raised to a vicariate in 1751 by Bishop Morel de Santa Cruz, with Saint Blaise as patron. A tremor in 1822 destroyed it; after further damage in 1826, the present calicanto church was built in 1827 on the old foundations.

The church is dedicated to Saint Blaise, named patron when Bishop Morel de Santa Cruz raised it to a vicarage in 1751, and cofradías devoted to various saints were founded there. Excavations in 2012 found about 154 people buried between 1600 and 1813, when cemeteries did not exist and burials took place inside churches.

The church stands on the central plaza of Nicoya, facing the town park, and is reached on foot from the surrounding streets. It was closed temporarily after the 2012 Sámara earthquake cracked the vault, walls and bell gable, so check locally whether the interior is open before planning a visit. When services are held, entry to the nave may be restricted.

Despite its centuries of existence, the structure has undergone significant changes through various restoration efforts over time. Recent renovation work aimed to bring it closer to its original appearance by using materials and techniques that honor historical methods.
