The Memorial Presbyterian Church, built by railroad magnate Henry Flagler, has the distinctive look found all around St. Augustine's old town. It was built with poured concrete (cement, sand, and coquina shell) and has beautiful terra cotta ornamentation over the exterior. Created in Spanish Renaissance style, it was inspired by St. Mark's Basilica in Venice.

In 1889, Henry Flagler built the church in honor of his grown daughter who died that year. Flagler is buried in the church, along with family members.
Go inside and check out the peaceful blue interior and Tiffany glass windows.
Another religious site to visit is the Mission Nombre de Dios, an adorable ivy-covered chapel that is a pilgrimage site (you need to drive to it).
