Old Lachlan Castle, Medieval castle ruins on Loch Fyne, Scotland.
Old Lachlan Castle is a medieval castle ruin on the shore of Loch Fyne in Argyll and Bute, Scotland. The remains consist of stone walls and foundations that trace two tower houses arranged within a shared enclosure.
The castle was built in the early 15th century on a site that had already been used as a stronghold a century earlier. Control of the castle passed out of Maclachlan hands in the 18th century after the clan sided with a losing political cause.
The Maclachlan clan still has a presence in the area today, and their ancestral seat draws people who want to trace the family's roots along the loch shore. The name Lachlan itself comes from the Gaelic word for the land of the Norse, pointing to the deep Scandinavian connections of this part of Scotland.
The ruins are reached by a short walk along a marked path from a nearby parking area, and the ground around the remains is uneven and rocky. Sturdy footwear is a good idea, as some sections require care when moving between the wall remnants.
An old well sits between the two tower foundations and is still visible today, positioned at the center of the original layout. Its placement suggests it was a shared resource between the two towers, which functioned as separate structures within the same enclosure.
