Iglesia de Nuestra Señora del Rosario, Colonial religious building in Ischilín Department, Argentina.

Iglesia de Nuestra Señora del Rosario is a colonial church in Ischilín built from stone and limestone, with brick detailing and buttresses along its walls. A barrel-vaulted portico projects from the main structure, sheltering the entrance. The building is a National Historical Monument of Argentina.

Construction began in 1706 on land provided by the López de Ayala brothers, with support from local residents and other contributors. The church served as a religious center for the early settlement of this region.

The carved wooden pulpit, decorated with two-headed eagles and lions, is the work of local craftsmen; the two-headed eagle was a Habsburg emblem, so the carving ties the church to the Spanish colonial period. The church is the focus of the annual feast of Our Lady of the Rosary, when the image is carried through Ischilín.

The church stands on the main square of Ischilín, a small settlement in the northern part of Córdoba Province reached by provincial roads branching off Ruta Nacional 9. The trip from the city of Córdoba covers roughly 100 km, so most visitors come by car and combine the stop with the surrounding villages of the Ischilín department.

The carob tree beside the church is known as the Algarrobo de Ischilín and is estimated to be over 400 years old, predating the 1706 construction. Local accounts hold that the López de Ayala brothers rested beneath its shade before granting the land for the church.
