"Napoléon and his armies marched through it; revolutionaries and Nazis gathered beneath it; the Berlin Wall ran right behind: It’s safe to say that Berlin ’s iconic Brandenburg Gate, completed in 1791, has pretty much seen it all. Designed by Carl Gotthard Langhans, who drew inspiration from the entrance to the Acropolis in Athens , the gate is best approached via Unter den Linden, the tree-lined boulevard that runs between the gate and the former Royal Palace. You can combine a visit here with nearby sights such as the Reichstag, Tiergarten Park, and the Memorial to the Murdered Jews of Europe. Since 2016, an impressive high-tech museum at the gate has offered a history of the city through the perspective of the iconic structure."
