Built between 1788 and 1791, Berlin's most recognisable symbol has witnessed all the key events of Germany's tumultuous history. Perhaps today its most vivid association is with the country's relatively recent reunification. An absolute must-see.
If you're visiting Berlin for the first time, a walk through the venerable Brandenburg Gate is a rite of passage. Originally built at the behest of King Friedrich Wilhelm II, the structure forms the dramatic endpoint to the showcase boulevard Unter den Linden. The legendary Hotel Adlon and the US embassy are situated along its route, and the Reichstag is just a few minutes' walk away.
The Brandenburg Gate was so badly damaged during the Second World War that it had to be replaced by a copy. Today you can visit its tranquil Raum der Stille, or Room of Silence, which is situated in one of the side wings. It's the perfect escape from the hustle and bustle of city life.
