Old Ordnance Survey Maps of Caernarvonshire


We have now built up quite a respectable series for Caernarvonshire, and more maps will follow. Here are the details. Further information on individual titles is given on our On-line Mapshop.

  • 6.12 Bangor 1913 - published 2001; introduction by Alan Godfrey. Bangor grew rapidly during the 19th century on its importance as a slate exporting port. The railway also became an important feature, the station on a cramped site between two tunnels. By 1901 the population was over 11,000 and this map vividly portrays the cramped housing in the Hirael district. It forms a group with the following Anglesey maps and an index map is available here.

  • 15.04 Caernarfon 1913 - published 2000; intro by Alan Godfrey. Famous for its great castle, and for the investitures of Princes of Wales, Caernarfon was also a major port in the 19th century and this map shows the railway serving the quayside. The town is packed with interest, both ancient and modern, clearly shown on this detailed map.
  • 16.08 Llanberis 1912 - published 2005; intro by Derrick Pratt. Numerous quarries, inclines and railways, including part of the Snowdon Mountain Railway.
  • 19.13 Betws-y-coed 1911 - published 2004; intro by Derrick Pratt. A double-sided map covering this tiny town in the Conwy Valley.


    We now have a group of maps for the varied towns on the Llyn Peninsula. Criccieth has its mighty castle, together with its Lloyd George connections and is perhaps an ideal base from which to explore the area. Pwllheli is well known as the terminus of the Cambrian Railway, but it was once a busy shipbuilding centre, and our map reveals two unusual tramways. Tremadog was a planned town, and our map also includes the Cambrian station and today's Welsh Highland terminus. Porthmadog is famed for its Festiniog Railway, but was also a busy harbour.

  • 34.12 Tremadog 1913 - published 2003; intro by Alan Godfrey
  • 34.13 Criccieth 1913 - published 2002; intro by Alan Godfrey
