San Blas de Illescas Church

San Blas de Illescas Church is a Catholic worship place in central Coamo with a two-level bell tower structure featuring open arches and bells positioned above the main roof. The front has ceremonial steps with cast iron railings and Spanish Colonial details throughout.

Construction of this church started in 1661 and reached completion after major renovations in 1784, making it one of Puerto Rico's oldest religious buildings. Those 1784 renovations shaped much of what visitors see today.

This place remains the main parish church for Coamo, where locals gather for weekly Mass and annual celebrations honoring San Blas. The community uses it year-round for important religious occasions.

The building sits on Mario Braschi Street at Coamo's Town Plaza and opens to visitors during the week. Guided tours are available, and it is helpful to arrive in the morning when light hits the front facade well.

The building mixes Spanish Colonial features with Baroque touches, which shows up in its curved front and decorative details. This style is uncommon on Puerto Rico, making the structure stand out visually.
