Located at the point where three lochs meet, Eilean Donan in Scotland is truly blessed when it comes to its spectacular setting. While the original castle is thought to have been built on the small island sometime in the 13th century, the current romanticized and reimagined reincarnation only dates to the 20th century.

Although its crumbling grey walls and undistinguished features may not look quite as impressive as many other castles, it is its gorgeous surroundings that really set it apart. Having featured in countless films and television shows over the decades, Eilean Donan is certainly one of the most famous and recognizable castles in the whole of Europe.
