Grangegorman, up until 2005, was regarded as the St Brendan’s institution and the immediate area surrounding it. To the east it bordered on Broadstone, to the west the boundary was Stoneybatter and Prussia Street. To the south it bordered on Smithfield and to the north there was the old cattle market and the North Circular Road.
The Royal Irish Academy say:-
‘The Grangegorman site is an area of approximately 73 acres, north of the River Liffey and south of the Royal Canal. It is bounded by the North Circular Road to the north, Prussia Street and Stoneybatter to the west, and Brunswick Street to the south.’
Under the Grangegorman Developement Agency Act 2005 the neighbourhood was re-defined as:
‘The Grangegorman neighbourhood shall comprise the electoral divisions (wards) of Arran Quay A, Arran Quay B, Arran Quay C, Arran Quay D, Arran Quay E, Inns Quay B, Inns Quay C and Cabra East C (as at 18 May 2005)’
Under this Act the Grangegorman Site was defined as:-
‘Those properties situated at Grangegorman in the City of Dublinwhich are delineated with a red verge line on the Ordnance Survey Ireland map marked “Grangegorman Development Area”’
Grangegorman Road Lower bisects what is referred to now as the Grangegorman Site and to locals this is what they regard as Grangegorman. Some long time residents of the area who once worked in the hospital refer to it as just ‘The Gorman’.
