The Circuit of Ireland International Rally is an annual automobile rally, which was first held in 1931 making it the third oldest rally in the world. The most recent event was held in 2016. The Circuit, as it is colloquially known, is organised by the Ulster Automobile Club and is traditionally held over the Easter holiday weekend. It normally starts and finishes in Northern Ireland, although over time the lengthy route of the event has typically included large segments in the Republic of Ireland as well. Most of the event's special stages are laid out on paved public roads that are closed to other traffic.
