Trump Turnberry Resort (Ailsa)

Opened in 1906 to an original design by Open champion Willie Fernie, the Ailsa course was all but destroyed when the site became an RAF airfield in both World Wars, before architect Mackenzie Ross rebuilt it from the ruined runways between 1949 and 1951, with Martin Ebert further remodelling the course in 2015-16. Set beneath its famous lighthouse with views across to Ailsa Craig and Arran, it has hosted four Open Championships, most memorably Tom Watson's epic 1977 'Duel in the Sun' victory over Jack Nicklaus and his own near-miss, aged 59, in 2009.
