Rothesay Castle

Rothesay Castle stands on the Isle of Bute in western Scotland. A ruined royal residence, it occupies a low mound near the former shoreline. The castle’s most striking feature is its massive circular curtain wall, built in the 13th century by the Stewart family. Four round towers once strengthened the wall, though only the north-west tower remains intact today. A broad moat surrounds the ruins, now partly shaped and cleared after 19th-century restorations. The site also includes a 16th-century forework with royal lodgings and a chapel inside the old walls. The castle’s history is marked by sieges and royal connections. Norwegian forces attacked it in the 13th century, breaking part of the eastern wall with axes. Robert the Bruce captured it in 1311 during the Wars of Independence. Later, kings Robert II and Robert III made it a favoured residence, and the title Duke of Rothesay began here. The castle survived sieges by the Earl of Ross and the Earl of Lennox before being damaged during Cromwell’s occupation and the Earl of Argyll’s rising. Visitors walk along the raised curtain wall, which offers fine views over Rothesay and the mainland. The surviving north-west tower still shows its three storeys and arrow slits. Inside, the chapel and the forework’s royal lodgings remain visible, along with the Pigeon Tower, converted from one of the original round towers. The moat, once linked to the sea, now frames the ruins. The castle’s restored sections reveal its layered past, from medieval battles to 19th-century repairs.
