St. Johns County is one of Florida’s two original counties, established in 1821 when the United States acquired Florida from Spain. Its county seat, St. Augustine, is the oldest continuously inhabited European-established city in the continental United States, founded by the Spanish in 1565. Over the centuries, the area came under Spanish, British, and eventually American rule, creating a unique blend of architectural styles and cultural influences. From colonial forts and cobblestone streets to grand hotels from the Gilded Age, the county reflects a rich and layered past. Its location on the Atlantic coast made it a significant center for trade, military activity, and tourism, and its historic legacy continues to shape the region’s identity today.
As St. Johns County has grown, it has managed to preserve its historic charm while embracing thoughtful development. St. Augustine’s historic district remains a cultural centerpiece, while thriving communities like Ponte Vedra Beach and Nocatee offer modern amenities and residential appeal. This balance between preservation and progress has made the county a standout in Northeast Florida.
