These impressive stone buildings let visitors step back in time to see the rich cultural heritage and smart designs that protected St. Augustine during its early days. Dive into the past and explore these famous landmarks that make St. Augustine a must-visit for history lovers.
Castillo de San Marcos
In 1672, construction began on the Castillo de San Marcos, and it took 23 years to complete. This fort was built from a stone called coquina, which is a limestone made with seashells and was tougher than earlier ones and could withstand attacks and fires. Even when British forces attempted several times to conquer it, they couldn’t break through its walls. After the Treaty of Paris in 1763, the fort changed hands from the Spanish to the British and became a prison during the Revolutionary War. In 1900, it ceased operation as an active military site. Shortly after, in 1924, the fort became a celebrated national monument, taking back its original Spanish name, Castillo de San Marcos.
At this fort, you can watch history come to life. Climb the ancient walls for a stunning view of Matanzas Bay and the city. Inside, you’ll find exhibits with old maps and artifacts that tell more about the fort’s history. The park rangers also host educational programs and fun events like reenactments and daily cannon firings, making history engaging for everyone. The Castillo is easily accessible as a stop on the Old Town Trolley.
Fort Matanzas
Built in 1742, Fort Matanzas was designed to protect a vulnerable back entry point into St. Augustine. After a close call during a 39-day siege in 1740, the Spanish realized they needed a fort at Matanzas Inlet. Using convict and slave labor, they quickly set up this smaller fort to stop any future threats. Today, Fort Matanzas reminds us of the lengths to which the old city went to protect itself. The fort’s strategic placement and design reflect the multicultural influences of Spanish and native engineering techniques that have shaped St. Augustine’s defense structures.

Zorayda Castle
Built in 1883 by Bostonian entrepreneur and architect Franklin W. Smith, Villa Zorayda is a stunning example of Moorish Revival architecture. Inspired by the Alhambra Palace in Granada, Spain, Smith sought to recreate the opulence and mystique of this iconic landmark in the heart of St. Augustine. His extensive travels and fascination with ancient civilizations fueled his desire to create not just a home but an educational experience.
Smith’s innovative use of poured concrete, a first for Florida, allowed him to construct a fireproof and durable structure. This groundbreaking technique would later influence the architecture of St. Augustine, including Henry Flagler’s iconic buildings.
After serving as Smith’s winter retreat, Villa Zorayda transformed into the Zorayda Club, a social hub for St. Augustine’s elite. The building later hosted a gambling casino and speakeasy before becoming a museum in the 1930s under the ownership of the Mussallem family.
The Mussallems dedicated their lives to preserving this architectural treasure. Through generations of stewardship, they meticulously restored and maintained the villa, ensuring its legacy for future generations. Today, Zorayda Castle offers visitors a glimpse into a bygone era, showcasing the rich history of St. Augustine and the artistic vision of its creators.
