Features include Slemish Mountain, Carninard, Tiftarney, Sallagh Braes, the Ballymena & Larne railway, the Ballymena & Parkmore Branch, Slievebane. On the reverse we include a more detailed map of the small town of Broughshane.
It is not possible to list the many hamlets, farmsteads and other topographical features shown on these maps. However, you may find it useful if we list the towns and principal villages or church parishes that are included on this map. Links are given for those for which detailed large-scale maps are also available.
