Royal Portrush Golf Club (1888): The only venue to host the Open outside England and Scotland when it hosted in 1951. With the Troubles in Northern Ireland significantly diminished since the 1998 Good Friday Agreement, and after the successful hosting of the Irish Open it returned as host in 2019. The course underwent significant changes before the 2019 Open, including replacing the 17th and 18th holes, which also provided the space for spectators and corporate hospitality that a modern major requires.
