Here is information about Sheet 58:
This Inch to the Mile map covers the central area of County Monaghan, with coverage stretching from Clones eastward to Monaghan and Castleshane, and southward to Ballybay. On the reverse we include a detailed map of Ballybay itself, showing its town crentre, including railway station, with individual houses neatly shown.
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.
