It’s not THE VATICAN but ruminate on how much geospatial data must be stored in The Vatican Microfilm Library and Pius XII Library in St. Louis that house the largest collection of manuscripts on microfilm outside the Vatican. They have a NEH and Mellon Fellowship for $1,750.00 per five-week period to visit the library but it is only open to graduates and post-graduates. You are probably saying to yourself, “Microfilm?” but they seem to have some digital material that may only be consulted in the reading room. The Vatican has many famous maps including the Gallery of Maps which were painted in the 1500′s.
