Was it possible to cross 7 bridges in the old East Prussian city of Konigsberg exactly one time each? Leonhard Euler proved it impossible in 1735 and laid the foundation of graph theory and topology.

The United Kingdom and the Soviet Union solved the problem again during WWII, by destroying two of the bridges while bombing the city, which made it possible to cross each of the remaining 5 bridges exactly one time each. After the war, the Soviet Union seized control of the city and renamed it Kaliningrad.
