The Brandenburg Gate is a former city gate, rebuilt in the late 18th century as a neoclassical triumphal arch and now one of the most well-known landmarks of Berlin. It is the only remaining gate of a series through which Berlin was once entered. The gate is the monumental entry to unter den Linden, the boulevard of linden trees which formerly led directly to the city palace. It was commissioned by King Frederick William II of Prussia as a sign of peace and built from 1788 to 1791. Having suffered considerable damage in World War II, the Brandenburg Gate was fully restored. During the post-war Partition of Germany the gate was inaccessible immediately, because it was next to the Berlin wall. The area around the gate featured in the media coverage of the opening of the wall in 1989.
