History+
The construction of Innes Chonnel Castle is attributed to the first half of the 13th century, likely by members of Clan Campbell. In 1315, Cailean Mór, also known as Colin Campbell, acquired extensive lands in what is now the Argyll and Bute region, underscoring the castle's importance to the clan. In the 15th century, extensive alterations were made to the castle courtyard, although the original footprint of approximately 25 by 25 meters largely remained. Until the late 15th century, Innes Chonnel Castle served as the main seat of Clan Campbell before being replaced by the newly built Inveraray Castle.
