Here is information about Sheet 61:
This Inch to the Mile map covers the Co Down coast around Dundrum Bay, with coverage stretching from Ardglass southward to Annalong.
The map includes the seaside resort of Newcastle, Dundrum Castle, Tyrella sands where the great steamship, Great Britain, was beached, and the busy fishing port of Ardglass. On the reverse we include a detailed map of Ardglass, showing the station, harbour, various castles, tramway, etc.
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.
