Below are listed the 13 Historic counties of Wales. These county boundaries were in common use from medieval times until the mid 1970s when 'administrative countries' became widely used to represent local councils administrative areas. As almost everything I research and discuss applies to sites with origins prior to 1970, I prefer to use the historic counties. If you're looking to see if we've visited a particular village and you're not sure why county it would have been in, please try county it would have been in, please try visiting the The Gazetter of British Place Names ​website and searching their database. We are not affiliated websites, but they are a useful resource when learning about the historic counties of the UK.
