This was a fun exercise!

Reading Armitage-Smith’s biography of John of Gaunt recently, I was intrigued to read that Gaunt held over 30 castles in England and Wales, the most of any noble during the Fourteenth Century. Armitage-Smith handily lists all of the castles, so I have used a Google Maps editing tool to locate these and publish them on the site.

The Tool is Map Maker, and the map I created is here.
