Old Ordnance Survey One-Inch Maps


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. Almost 200 titles are now available 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.

The maps are neatly folded and each includes a specially written introduction to the area. Maps can be purchased on our On-line Mapshop where further information about titles is given. Visit the One Inch Page for a full list of Inch to the Mile Maps, or The Index Page for a full list to the series and details of Prices.

Here is information about Sheet 164:

  • One Inch Sheet 164 SW Montgomeryshire 1908 - published 2001; introduction by Alan Leather

    This One Inch to the Mile map covers much of southern Montgomeryshire, with coverage stretching from Y Foel, Pen Plynlimon-Arwystli and Plynlimon Fawr eastward to Penstrowed; and from Carno southward to Llangurig. Much of the area is mountainous, especially to the west, but roads and railways go up the valleys of the Severn and the Carno. Llanidloes, near the centre of the map, is the only town, although Caersws, once home to a Roman camp, has a workhouse. The Cambrian Railway is shown and also a long stretch of their Mid Wales line, the Van Railway, and the route of the already disused line to Llangurig. Railway historians will also enjoy our backing map, an extract from Montgomery Sheet 41.12, which shows Y Fan in detail, including the Van Mines, mineral tramlines, and the end of the Van Railway, including Garth & Van Road station.


    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.

  • Montgomeryshire: Aberhafesp, Caersws, Carno, Llandinam, Llangurig, Llanidloes, Llanwnog, Mochdre, Penstrowed, Trefeglwys.
