San Carlos Borromeo Church

San Carlos Borromeo is a parish church in Aguadilla featuring two octagonal towers on its facade. The building contains two side aisles, a flat roof, and uses a groin vault structure in the apse instead of a traditional dome.

The church was built in 1783 on Aguadilla's main plaza, serving as a focal point for the developing town. It gained recognition on the National Register of Historic Places in 1984.

The church honors Saint Charles Borromeo, a significant figure in Spanish religious tradition. Visitors can see how the colonial architecture shapes the space for worship and community gatherings that still take place here.

The church is located in downtown Aguadilla and remains accessible throughout the week. Visitors should note that access may be limited during religious services and community events.

The groin vault in the apse sets this church apart from many others across Puerto Rico, which typically employ dome designs. This architectural choice reflects a different influence in how the interior space was conceived.
