Present landscape
On the ground you are reading earthworks, slope, sightlines and interpretation rather than standing masonry.
What it was
Dunoon Castle stood on Castle Hill as a major medieval stronghold tied to regional power, royal visits, and the defensive history of the Clyde.
What was lost
The visible mass of the castle, much of its readable layout, and the sense that Castle Hill was once Dunoon’s primary power-centre were all lost over time as the site fell into ruin and stone was reused.
What remains now
Visitors still have the hill, the outlook, and a few fragmentary clues, but they need interpretation to understand what once stood there.
