Old Ordnance Survey Inch to the Mile Maps

  • These maps normally cover an area of about 18 miles by 12 miles and are especially good at showing railways, roads and canals, and at giving a broad view of a wider area. Each includes an introduction and a more detailed map of a small town or village. They are available through our On-line Mapshop

  • Here is information about Sheet 150:

  • One Inch Sheet 150 Dinas Mawddwy & District 1904 - published 2002; intro by Derrick Pratt. ISBN.978-1-84151-408-6

    This Inch to the Mile map covers a large area of Montgomeryshire, with a smaller section of Merioneth in the NW corner. Coverage stretches from Cemmaes Road station eastward to Llanwyddelan, and from Dinas Mawddwy and Craig Dunant southward to Talerddig and Newydd Fynyddog. Features include stretches of the Cambrian Railway and the Mawddwy Railway, but the map is dominated by hilly terrain and ranges of the Cambrian Mountains. On the reverse we include a detailed map of the centre of Dinas Mawddwy.

    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.

  • Merioneth: Dinas Mawddwy, Mallwyd.
  • Montgomeryshire: Cemmaes, Darowen, Dolanog, Garthbeibio, Llanbrynmair, Llanerfyl, Llanfihangel-yng-Ngwynfa, Llangadfan, Llanllugan.
