Dunollie Castle
Caisteal Dhùn Ollaidh
Dunollie Castle is a small medieval castle ruin on a hill north of Oban on the west coast of Scotland. The visible remains are largely 15th-century masonry standing on a high promontory with broad views to the island of Kerrera, the town and harbour. The site and surrounding grounds are managed as part of the Dunollie Museum, Castle & Grounds by a preservation trust.

As it stood in 1450
What Dunollie Castle looked like in its prime.
A compact ruined stone castle crowns a grassy promontory north of Oban, facing the Sound and the island of Kerrera. The surviving fabric is mainly 15th-century grey masonry: grouped wall lines and foundation footprints forming a small hilltop stronghold within older earthen banks. The site opens to sea views over the town and harbour below and sits within maintained grounds where a historical herb garden has been identified; Dunollie House lies down the slope.
Its story
The story of Dunollie Castle.
Dùn Ollaigh, Royal Centre of the Cenél Loairn
Long before the masonry that survives today, the high promontory north of Oban carried a stronghold of the early Middle Ages, when Dunollie was the royal centre of the Cenél Loairn within the kingdom of Dál Riata. The Irish annals record that Dun Ollaigh was attacked or burned three times in fifteen years — in 686, in 698 and in 701.
The man credited with destroying the site in 701, Selbach mac Ferchair (died 730), King of Dál Riata, rebuilt it in 714. Excavations in the 1970s suggest that this early fortification was abandoned at some point in the 10th century.
Somerled's Heirs and the Lordship of Lorne
The country around Dunollie became part of the semi-independent Kingdom of the Isles, ruled in the 12th century by Somerled. On his death his descendants, the MacDougalls, became Lords of Lorne; his son Dougall held most of Argyll along with Mull, Lismore, Jura, Tiree, Coll and many other islands. Excavation shows the promontory refortified with an earthwork castle in the 13th century, or possibly as early as the late 12th, the builder perhaps Dougall himself or his son Duncan.
Ewan MacDougall, Somerled's great-grandson and third chief of the MacDougalls, switched the clan's allegiance in the mid-13th century. Allied at first with Haakon IV of Norway, from the 1250s he remained loyal to the kings of Scotland.
Dalrigh and the Pass of Brander, 1306–1308
Ewan's grandson John MacDougall took the opposite side. With his kinsmen the Comyns he stood with the Balliols against the interests of Robert the Bruce, and in 1306 his army defeated Bruce at the Battle of Dalrigh. The reckoning came two years later: Bruce returned in 1308 and crushed the MacDougalls at the Battle of the Pass of Brander.
The MacDougall lands of Lorne were forfeited and handed to the Campbells, though Dunollie and other estates were recovered later in the 14th century. The ruins standing on the rock today are largely of the 15th century, raised after that recovery.
Argyll's Capture and the Move Downhill, 1644–1746
The Marquis of Argyll captured the castle in 1644, and it was not returned to the MacDougalls until 1661. In 1746 the family abandoned the old stronghold altogether and built Dunollie House on the slope just below the ruins.
The castle has been a scheduled monument since 1931. The MacDougall of Dunollie Preservation Trust now cares for the historic buildings and the collections held at this ancestral site, running them as Dunollie Museum, Castle and Grounds; the remains of a historical herb garden have been found in the grounds.
