I appreciate the effort. That would have been interesting. According to my research it's even more fun than it being a "city." It was a land called Rome, with Seven Hills, On the Tibur, Owned by Pope, Francis (note the comma).

This land was 400 acres. I mapped out the dimensions (given in old timey measurements in the link above) and it contains most of the Capitol Mall, the White House, the Federal Reserve, and all sorts of other interesting D.C. establishments in that area. I think the Washington Monument is on the southeast corner of it (or close to it). It was given to the U.S. Government so the masons could build their pentagonal spell forms out of it.

All roads lead to Rome.
