Here is information about Sheet 21:
This Inch to the Mile map covers Larne, Larne Lough and Islandmagee. Coverage stretches from Ballgalley Head southward to Glenoe. Inevitabvly there is rather a lot of sea on this map, which also includes the Maidens or Hulin Rocks. On the reverse we include a detailed map of the village of Glynn.
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.
