Brochel Castle is a prominent ruin standing on a rocky volcanic plug approximately 15 metres high on the island of Raasay in the Inner Hebrides of Scotland. Built allegedly by Calum, first Chief of Clan MacLeod, the castle existed by 1549 and represents an ingenious fusion of natural rock and masonry. The fortress commanded a strategic position overlooking a sheltered natural harbour, allowing the MacLeods to control their mainland possessions. In the late 17th century, as the Macleods relocated to more comfortable residences, Brochel began its decline into picturesque ruin. Today, the castle remains a dramatic landmark visible across the Inner Sound, accessible to visitors interested in clan history and Highland fortifications.
