Standing at the southwestern entrance to the Sound of Mull, the Lismore Lighthouse (also known as Eilean Musdile) serves as a vital guardian for mariners navigating the Firth of Lorn toward the Inner Hebrides. This historic structure was designed and built in 1833 by the renowned civil engineer Robert Stevenson. A titan of Scottish engineering, Stevenson was the patriarch of a “lighthouse dynasty” and the grandfather of the celebrated author Robert Louis Stevenson. For nearly two centuries, his design has withstood the volatile Atlantic weather of the Argyll coast, remains a testament to the enduring legacy of the Stevenson engineers.
