Heritage listing
Old Castle Lachlan, also known as Castle Lachlan, is a ruined 15th-century castle on the shore of Loch Fyne, on the Cowal Peninsula, in Argyll and Bute, west of Scotland. It was probably built by Clan Maclachlan on lands first recorded in 1314 as "Castlelachlan". Nothing remains of this fourteenth-century castle. Instead, the enclosure of Old Castle Lachlan appears to date to the early fifteenth century, whilst the internal buildings seem to date to the later part of the century. The castle remained a residence of the clan's chiefs until New Castle Lachlan was built as a replacement in 1790, 0.8 kilometres (0.5 mi) east-north-east. It is protected as a scheduled monument.

Background
History
The clan is descended from Lachlan Mor ('Great Lachlan') a powerful chieftain who lived on the shores of Loch Fyne in the 13th century. Lachlan Mor is said to be descended from Anrothan O'Neill an Irish prince who left Ireland in the 11th century. Yet despite MacLachlan's presence little is known about the construction and creation of Old Castle Lachlan. The earliest references date back to 1314, and it is believed to have been built by Clan Lachlan.
