Mapa de Pueblos Abandonados
This Google Map shows the locations of abandoned towns and villages in Spain. The red map markers indicate locations that have full descriptions and links to articles on the site's blog.
If you click on a a map marker the information window includes a zoom in button. When viewing the map it is interesting to switch to satellite view and zoom in on the abandoned town. I think the site has missed a trick by not adding a Street View option. It would be great to see the Street View imagery of these abandoned towns, although I suspect Street View imagery may not be available in many of them.
