Old Lachlan Castle

Old Lachlan Castle is a medieval fortress in ruins on the shores of Loch Fyne in Scotland. The site preserves stone walls and foundations that outline the original structure and its internal divisions.

The fortress was built in the early 15th century to replace an earlier stronghold documented in 1314. In the 18th century, the clan lost control of the site due to their involvement in a failed political uprising.

The site served as a seat of power for the Maclachlan clan for centuries, with their presence woven into the landscape. People in the region still know the place through the family's long association with this part of the loch.

The site is reachable via a marked path from the parking area, with the walk taking about 10 minutes. The ground is uneven and rocky, so sturdy footwear is recommended.

Within the castle grounds stand two tower houses that once served as separate structures, positioned on either side of an ancient well. This well remains visible beneath the stone remnants and shows how the original site was laid out.
