Favorite Spain Map Site

There are a lot of different map sites on the internet that can be very useful in genealogy. Historical maps and atlases are ideal, but can be hard to find or not easily accessible online. Map sites that have sufficient geographic coverage are essential in our genealogy research. Some other things I look for include:

• Historical accounts of the town or city
• Photos
• Collaboration--a website that is active and "alive" indicate that they are good.

One of the sites that I use the most is: http://www.pueblos-espana.org The site is searchable and browsable. It lists all the Spanish provinces, and all the towns within each province. Check out the site and let me know what you guys think.
