An excellent real world site to visit for maps is the incredible Theban Mapping Project. Its site can be found at:

http://www.thebanmappingproject.com/

also http://www.kv5.com/ will work as well.

The site uses a flash interface to access maps of the Necropolis of Thebes in Egypt as well as numerous tombs in the Valley of the Kings. If you are ever looking for info on ancient funerary structures, the Theban Mapping Project is hard to beat.
