Ventspils is a Latvian port city on the Baltic Sea. It's bisected by the Venta River. The old town, with cobblestone streets and 17th-century storehouses, is centered on Town Hall Square and Market Square. The 13th-century Castle of the Livonian Order now houses Ventspils Museum, with exhibitions on the castle and the city. Close to the city's beach, Ventspils Water Park has slides and pools.
