Historic Site · Hidden Gem · Tourist Spot
Old Castle Lachlan, also known as Castle Lachlan, is a ruined 15th-century castle on the shore of Loch Fyne, within the Cowal Peninsula, in Argyll and Bute, 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.
Near the castle is Kilmorie Chapel, the resting place of the Maclachlan clan chiefs and one of the few remaining medieval church buildings in the West of Scotland.

  • Lovely scenic walk to the castle. Pathway was will maintained. Not much to see inside as it was been blocked off. Can get a sense of the space and surroundings to help you connect with the past. Good for a walk with the family with easy access to water if you want to get your feet wet.
