The Ballysillan Road leads off the Crumlin Road and is a major area of loyalist housing. Containing the likes of the Silverstream and Carr's Glen districts, the Ballysillan Road continues as far as the North Circular Road, which, in turn, links to the Antrim Road, which also began at Carlisle Circus. During the Northern Ireland Troubles Ballysillan was noted as a centre for loyalist paramilitary activity and was the home base of "D Company" of the Ulster Volunteer Force (UVF) under the command of John Bingham Along with Glenbryn, Ballysillan was also at the centre of a loyalist feud in 2003 when Jimbo Simpson, who had recently been ousted as head of the North Belfast Brigade of the Ulster Defence Association (UDA), attacked a number of houses in the area as part of a failed attempt to retake control of the Brigade and force out his replacement William Borland. The Crumlin Road entrance to Ballysillan houses another historic church, the Ballysillan Presbyterian Church. Due to its elevated and exposed location Ballysillan, which takes its name from an Irish language expression meaning "townland of the willow grove", is one of the coldest areas of the city during winter.
