Konstanz

Konstanz is a university city with approximately 83,000 inhabitants located at the western end of Lake Constance in the south of Germany, bordering Switzerland. The city houses the University of Konstanz and was for more than 1200 years residence of the Roman Catholic Diocese of Konstanz.
Because it almost lies within Switzerland, directly adjacent to the Swiss border, Konstanz was not bombed by the Allied Forces during World War II. The city left all its lights on at night, and thus fooled the bombers into thinking it was actually part of Switzerland.
