Here is information about Sheet 48:
This Inch to the Mile map covers an area of central County Down with coverage stretching from Lawrencetown eastward to Ballynahinch, and from Waringstown southward to Katesbridge. It includes the towns of Banbridge and Dromore, the three railways converging on Banbridge, Monahoora, Slievenisky, Slieve Croob, the source of the Lagan, the western side of Ballynhainch, Deehommed Mountain, mills and bleach works, etc. On the reverse we include a detailed map of the village of Waringstown.
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.
