Coeffin, Medieval castle ruins on Isle of Lismore, Scotland.
Coeffin is a medieval castle ruin on the Isle of Lismore, a small island off the west coast of Scotland. The remains consist of thick stone walls and foundations set on a rocky coastal headland overlooking the surrounding sea channels.
The castle was built in the 1200s by the MacDougall clan to control the sea routes between the Scottish islands. Over time it changed hands as power shifted in the region, and it was eventually abandoned.
The name Coeffin is said to come from a Norse princess named Beathag, whose spirit is believed by locals to linger at the site. Islanders still share this story today, and it shapes how visitors experience the ruins.
To reach the ruins, you need to take a ferry to Lismore and then walk from the landing point. Sturdy footwear is recommended because the ground is uneven and the weather on this part of the Scottish coast can change quickly.
Close to the main walls, an old stone fish trap is still visible at the water's edge, suggesting the headland was used long before any castle stood here. Nearby traces of an even older stone structure hint that this spot has been occupied for many centuries.
