The Colonia del Sacramento Historic District is known for its well-preserved colonial architecture and rich history. Founded in 1680 by the Portuguese along the Río de la Plata, the district changed hands during Portuguese and Spanish rule, resulting in a unique blend of architectural styles, and in 1995 UNESCO recognized the area as a World Heritage Site for its unique blend of Portuguese, Spanish and post-colonial influences. Visitors can explore the narrow cobblestone streets, historic buildings, and landmarks such as the lighthouse and the Cathedral of San Sacramento. The district also offers a variety of lodging and dining options, making it a vibrant destination for visitors.
