Here is information about Sheet 70:
This Inch to the Mile map covers parts of counties Armagh, Louth and Monaghan.
The map includes the towns of Dundalk, Carrickmacross and Crossmaglen, with coverage stretching from Laragh eastward to Jonesborough. Features include the railway from Dundalk to Carrickmacross etc, the Forkhill area, Louth village with its ruined abbey, Roche Castle, the south Armagh area, etc. On the reverse we include a detailed map of Carrickmacross.
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.
