Eilean Donan, Scotland

Eilean Donan is perhaps one of the most well-known medieval castles, easily recognized by almost anyone. Partly, thanks to being featured in the 1986 film Highlander, but also as one of the must-see places in the Western Highlands of Scotland. This highland gem is located on an island between three sea lochs – Loch Duich, Loch Long and Loch Alsh.

Historically, it was a stronghold for the Clan Mackenzie and was established in the 13th century. Unfortunately, the original castle suffered destruction in the 18th century during the Jacobite rebellions and was rebuilt in the 20th century.
