Architecture and continuing use
A massive circular curtain wall is strengthened by four round towers and a projecting residential gatehouse. Within it stand a chapel and other ranges, all set on a broad mound enclosed by a moat.
Its story
The castle developed through the Middle Ages as a stronghold associated with the Stewarts and the royal burgh. It was attacked, altered and later conserved; today its walls and moat form the historic centre’s principal monument.
Why it is included
Its unusual circular plan, royal associations and close relationship with harbour and burgh make it essential to understanding Rothesay’s origins.
What to notice
- Circular curtain wall and four round towers.
- Large projecting gatehouse known as the dungeon.
- Moat, mound and the castle’s position only a short distance from the harbour.
