Kingstown, the capital of St. Vincent and the Grenadines, is a major port city for the Caribbean island chain. The city features a series of surviving 19th century buildings, including St George's Cathedral, known for its beautiful stained glass, and the Romanesque Cathedral of the Assumption. In the wharf area, visitors can see structures built from the tile and red brick that was used as ballast on trading ships from Britain, or head up to Fort Charlotte for a stunning view of the city.
