Between 2006 and 2009 I researched and completed a PhD about videogames, mazes, and our relationships between real and virtual worlds. It meant I walked a lot of mazes in real life (as well as playing a lot of different videogames). I decided to map all of these mazes, for my own reference, but also to help anyone else that wanted to visit them. The original map had Google Maps as a base. I have since reworked it using Open Street Maps as the map base.
The map can be found here.
