1. Cathedral Basilica of St. Augustine: This national historic landmark is the oldest of the Catholic churches in St. Augustine, founded in 1565, but the current structure was completed in 1797. The architectural style combines Spanish Mission and Neo-classical design, and it’s one of the most impressive buildings in the area. Today, “America’s First Parish” continues over 450 years of history in the United States, offering Mass and parish activities to residents and visitors.
2. Memorial Presbyterian Church: Built by Henry Flagler in 1889 to honor his late daughter, this church consists of a Venetian-Renaissance architecture with intricate terracotta friezes, an enormous copper dome, and hand-carved mahogany details. To this date, this church is one of the most intact churches in St. Augustine. It looks much as it did when it was first constructed from the designs of noted architects Carrere and Hastings.
3. Shrine of Our Lady of La Leche: One of the smaller, unassuming old churches in St. Augustine to visit, this vine-covered historical shrine is known as the oldest in the US. It’s located within the Nombre de Dios Mission, also a treasure of history with a 208-foot stainless steel cross, which was a gift for the 400th anniversary of the mission. The Great Cross rises 208 feet above the marshes of the Matanzas River.
4. Trinity Episcopal Church: As the oldest example of all the Protestant churches in St. Augustine, there are a lot of beautiful details to see at this historical landmark. Intricate and original stained glass windows are one of the most impressive elements. One window is signed by Louis Tiffany, and others were created by noted stained and painted glassmakers.
