Unter den Linden ('Under the Linden trees' in English) is a famous boulevard in the city center named after its many linden trees and runs east–west from the Brandenburg Gate to the former site of the imperial palace. The linden trees were originally planted in 1647, but were cut down and used as firewood during the second World War. In the 1950s they were replanted and the Unter den Linden boulevard was brought back to its original glory.
