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. Over 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 232:

  • One Inch Sheet 232.1 NW Monmouthshire 1901 - Coloured Edition - published 2007; introduction by Derrick Pratt
  • One Inch Sheet 232.2 NW Monmouthshire 1914 - published 2006; introduction by Derrick Pratt

    We have published two versions of this map, showing how the area developed across the years. However, the 1901 version is notable as being our first OS reprint in colour and is taken from one of the early colour-printed versions of the One Inch map. These 'Small Sheet Coloured' maps are quite rare, and map collectors as well as historians will, we think, enjoy our reprint. Please note that the coloured map costs slightly more than the rest of ther series, £ 3.50.

    The maps each covers the north western part of Monmouthshire (today Gwent) with smaller portions of Brecknockshire and Glamorgan. Coverage stretches from Rhymney eastward to Llanvapley, and from Crickhowell southward to Abertillery. A major feature is the group of Valleys, with the industries and railways clustered around Rhymney, Ebbw Vale and Blaenavon; while to the east is Abergavenny with the Usk Valley. On the reverse of the 1914 version we include a map of Llechryd and Rhymney Bridge.

    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.
