Caisteal Ùisdein, known as Hugh's Castle, is a dramatic 16th-century tower house perched on a cliff overlooking Loch Snizort Beag on the Isle of Skye's Trotternish Peninsula. Built by Hugh MacDonald, a cousin who sought to challenge his uncle's authority, the castle later became central to a notorious historical incident involving a fatal mix-up of correspondence that exposed an assassination plot, resulting in Hugh's imprisonment in Duntulm Castle. The castle's remaining walls rise to approximately 20 feet high, offering glimpses into Scotland's turbulent clan history and the complex politics of the MacDonald dynasty. Located in a remote setting, it remains accessible to visitors seeking to explore Skye's atmospheric historical sites and dramatic landscapes.
