Castletown is a small town located on the southern coast of the Isle of Man, a self-governing British Crown dependency in the Irish Sea. The town was the island’s capital until 1869, and its historic centre is dominated by impressive stone buildings from the 18th and 19th centuries, including the Castle Rushen, a medieval castle that was once the residence of the island’s governors. Castletown is also home to a picturesque harbour, which was once a busy trading port, and the Old House of Keys, the former home of the island’s parliament. Today, Castletown is a popular tourist destination, with visitors drawn to its historic charm and beautiful coastal scenery.
