Torosay Castle on the Isle of Mull is a Victorian mansion completed in 1858, designed in Scottish Baronial style by acclaimed architect David Bryce for John Campbell of Possil. Originally named Duart House, it was renamed Torosay to distinguish it from the nearby Duart Castle on the Sound of Mull. The castle stands 1.5 miles south of Craignure and remains owned by the Campbell family, set within 12 acres of spectacular gardens featuring formal terraces with roses and perennials, woodland gardens with pools, alpine collections, and extensive rhododendron plantings. Though currently closed to the public, the castle's picturesque gardens are occasionally open, typically on the first Sunday of each month during the season, offering visitors a glimpse of Highland island life and Victorian architectural heritage.
