These maps are taken from the famous OS "Inch to the Mile" Maps. Though obviously far less detailed than the large scale maps for which we are perhaps better known, they provide an invaluable overview of a wider area, typically 18 miles across by 12 miles down. For transport historians they are invaluable for showing old railways, while all historians need them for their close depiction of topography, including parish boundaries. These maps also mean that we can offer historical coverage for small villages where a large scale map would not be commercially viable. We intend to publish the whole of England and Wales in this series which will comprise some 300 titles, and we aim to publish three new titles each month. The maps include historical notes and all (except the double-sided Tyneside title) also include a large scale map of a small town or village in the area.
Here is information about Sheet 231:
This One Inch to the Mile map covers an area at the north of the Valleys, with the industrial area around Merthyr Tydfil and Aberdare, and the much more rural part of south Brecknockshire, an area known as Fforest Fawr. Near the centre of the map is the village of Ystradfellte and we also include a detailed map of this on the reverse. The northern part of the Taf and Cynon valleys are shown, together with a portion of the Vale of Neath, and there are numerous railways, including the Neath & Brecon and the Brecon & Merthyr lines. Around Merthyr and Aberdare are collieries and ironworks, the disused Glamorganshire Canal, mineral lines; while Hirwaun and Blaengwrach are also included. The map stretches from Resolven northward to Beacons Reservoir, and from Pen-rhos eastward to Dowlais Top station.
It is not possible to list the many hamlets, farmsteads and other topographical features shown on these maps. However, you might find it useful if we here list the majority of the principal villages and church parishes that are included on this map. Links are given for those for which detailed large-scale maps are also available.
