A cone-shaped hill in Dunoon holds the scant remains of a castle that was once a royal residence. Dunoon Castle is a ruined medieval castle, now reduced to little visible structure beside Castle House.

The castle’s history includes Balliol conflict, Campbell keepership, Mary Queen of Scots’s visit and later military use during the world wars. Its surviving mound and surrounding area are protected as a scheduled monument.

What follows is drawn from published sources, with each claim labelled by how firmly it is established.

History

Dunoon Castle is first recorded in the 13th century. It may have been built as Stewart authority increased in Cowal.

In 1333 Edward Balliol besieged and took Dunoon Castle, then surrendered it to Edward III of England. Robert the Steward, later Robert II, retook the castle with help from Colin Campbell of Lochow.

By the 15th century Dunoon was a royal castle with the Campbells as hereditary keepers. James III undertook to repay Colin Campbell, 1st Earl of Argyll, for castle repairs in 1468 and made him keeper in 1472.

Matthew Stewart, 4th Earl of Lennox, took Dunoon and Rothesay in 1544 with English support. Mary Queen of Scots stayed at Dunoon Castle from 27 to 29 July 1563.

The Dunoon massacre of 1646 saw Campbells slaughter members of Clan Lamont. After the restoration of episcopacy under Charles II, Dunoon served for a time as a residence of the bishops of Argyll.

Military fortifications were established at Dunoon Castle during both world wars.
