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 120:

  • One Inch Sheet 120 Cerrigydrudion, Corwen & District 1904 - published 2002; intro by Derrick Pratt. ISBN.978-1-84151-427-7

    This Inch to the Mile map covers Corwen and the area to the west, a region divided betwen Denbighshire and Merioneth. Apart from Corwen there are no towns and few sizeable villages. Author Derrick Partt tells us that it was an area that 19th century travellers "contemptuously dismissed" as "little more than huddles of poor houses beaded erratically along Telford's Holyhead Road". But there is always much of interest on a one-inch map, including here stretches of long lost railways, and the Alwen Valley which was soon to be flooded for a reservoir. Much of the land is mountain and moorland, with some of the Berwyn Mountains and the Denbigh Moors or Mynydd Hiraethog. On the reverse we include an extract from Merioneth sheet 15.15, showing Llandrillo in more detail, complete with directory.

    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.

  • Denbighshire: Cerrig-y-Druidion, Clocaenog, Llanfihangel Glyn Myfyr, Llangym, Pentre Foelas, Yspytty-ifan.
  • Merionethshire: Bettws-Gwerfil-Goch, Corwen, Gwyddelwern, Llandderfel, Llandrillo, Llangar.
