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 249:

  • One Inch Sheet 249 Newport, Caerphilly & District 1894 - published 2003; introduction by Martin Culliford

    This Inch to the Mile map covers the area around and to the north of Newport and Caerphilly, including much of the eastern Valleys. Coverage stretches from Glyn Taff and Treharris eastward to Caerleon, with Goldcliff in the SE corner; and from Pontypool southward to St Bride's Wentlloog. Much the largest town is Newport with its expanding docks, but scattered development is shown over much of the map, notably along the valleys of the Taff, Rhymney, Ebbw, Sirhowy. Numerous railways run through these valleys, including the Taff Vale Extension, Rhymney Railway, Sirhowy Branch, Taff Vale Aberdare Extension, Brecon & Merthyr Railway, Barry Railway, Newport Ebbw Vale & Nantyglo Branch, Newport & Blaenafon Railway and others. Other features include the Monmouthshire Canal and Brecon & Newport Canal. On the reverse we include an extract from Monmouthshire Sheet 28.04 showing Llanvihangel Llantarnam.


    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.
