Unter den Linden
Berlin’s piece de resistance is packed with the gems of Prussia’s imperial architecture. Originally a bridle path, this show-off boulevard stretches from Schlossbrücke Bridge to Pariser Platz at the Brandenburg Gate (the city's greatest symbol of a fighting free spirit). Hitler chopped down the magnificent, namesake linden trees, and World War II left the avenue a wasteland. Restoration began in 1958, then intensified since the Fall of the Wall. Unter den Linden remains the essential stop for any Berlin visitor.
