The Brandenburger Tor is a monumental gate, which replaced an older city gate, built in the 18th century as a symbol of peace. It is situated at the end of Unter den Linden, a grand boulevard in Berlin, Germany. This gate is related with the worst moments of the Berlin's history and is probably the most well-known landmark in Berlin, it now stands as a symbol of the reunification of the two sides of this great city.
The gate led directly to the city palace of the Prussian monarchs. It was commissioned by King Friedrich Wilhelm II of Prussia as a sign of peace and built by Carl Gotthard Langhans from 1788 to 1791.
The gate consists of twelve Greek-style Doric columns, six to each side, forming five passageways. Citizens originally were allowed to use only the outermost two. Atop the gate is the Quadriga, a chariot drawn by four horses driven by Victoria, the Roman goddess of victory. In 1806, during Berlin's occupation by France, Napoleon ordered the quadriga to be taken to Paris. After the Battle of Waterloo, the quadriga was triumphantly taken back to Berlin, and it was turned into a symbol of victory, that's why the quadriga is called Victoria.
During WWII the Brandenburger Tor was badly damaged but not destroyed by allied bombing. After WWII, the gate was incorporated into the Berlin wall during the years of Communist government. Consequently, it became a symbol of a divided city.
With the fall of the wall in November 1989, people flocked to the reopened Brandenburger Tor to celebrate. Since the fall of the Berlin Wall, the gate has become the symbol of a reunified Berlin and a symbol of unity.
