Dunollie Castle is a small ruined castle located on a hill north of the town of Oban. The castle is open to the public as part of the Dunollie Museum, Castle and Grounds.
There was a fortification on this high promontory in 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 down three times, in 686, 698, and in 701. It was subsequently rebuilt in 714 by Selbach mac Ferchair (died 730), the King of Dál Riata credited with destroying the site in 701. Excavations in the 1970s suggest that this early fortification was abandoned some time in the 10th century.
The area around Dunollie subsequently became part of the semi-independent Kingdom of the Isles, ruled over by Somerled in the 12th century. On his death the MacDougalls became Lords of Lorne. Dougall, Somerled’s son, held most of Argyll and also the islands of Mull, Lismore, Jura, Tiree, Coll and many others in the 12th century.
Excavations show that Dunollie was refortified with an earthwork castle in the 13th century or potentially the late 12th century. The builder may have been Dougall, or his son Duncan. Ewan MacDougall, great-grandson of Somerled and the third chief of the MacDougalls, switched the clan's allegiance in the mid 13th century: initially allied with Haakon IV of Norway, from the 1250s Ewan remained loyal to the kings of Scotland.
In the 14th century Ewan's grandson John MacDougall, along with his kinsmen the Comyns, sided with the Balliols against the interests of Robert the Bruce. John MacDougall's army defeated the Bruce at the Battle of Dalrigh in 1306, but Bruce returned in 1308 and crushed the MacDougalls at the Battle of the Pass of Brander. The MacDougall lands of Lorne were subsequently forfeit and were given to the Campbells, though Dunollie and other estates were regained later in the 14th century.
The existing castle ruins date largely from the 15th century. The Marquis of Argyll captured the castle in 1644, but it was returned to the MacDougalls in 1661. In 1746, the MacDougalls abandoned Dunollie Castle and built Dunollie House just downhill from the castle ruins.
In recent years, descendants and members of Clan MacDougall have been encouraged by clan leadership to support local tourism and pay visits to Dunollie, as an ancestral site and important cultural location. Remains of a historical herb garden have recently been discovered in the castle grounds.
References:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
