Cool Monastary map
I'm running a Superhero campaign and have been on the lookout for use location maps to blow up (both literally and figuratively)
One of the most useful sources of maps has been the google image search
try an image search "floor plan" or floorplan then refine it with the sort of building your interested in.
its also useful to set the image size to Large so you can print it out A0 (I'll write more about this later)
I was looking for a monastery and this peach of a site popped out
I plan to post other good sites as I find them
This is a nice cutaway Cathedral
