Colonia del Sacramento
Colonia del Sacramento is a city in southwestern Uruguay, across the Río de la Plata from Buenos Aires. It's known for its cobblestoned Barrio Histórico, lined with buildings from its time as a Portuguese settlement. Set above the historic district is the 19th-century Colonia del Sacramento Lighthouse, offering sweeping river views. Nearby lies the Portón de Campo, remnants from the old city walls.
