Leonardo da Vinci -- The Architect?
"[M]any often overlook da Vinci in one of his most accomplished fields of endeavor: architecture... In fact, it took almost five hundred years for someone to actually build something explicitly based on one of da Vinci's designs. To date, this project stands as the only one of the Renaissance Man's architectural plans ever built... The project in question is the aptly named Leonardo Bridge Project in an Oslo suburb in Norway, which opened to the public on Oct. 31, 2001, and for which da Vinci completed the design in 1502."
