Since its original designation in 1983, Newry Conservation Area has been extended twice.
In 1992 the boundary was extended southward to incorporate the historic commercial spine of Hill Street/John Mitchel Place; the original 12th century settlement and areas abutting the canal/river.
In 2001 the area was extended northwards to incorporate the historical significance of the Newry Canal to the town.
