Kicking off our European Bucket list is perhaps one of Europe’s most quintessential cities. Berlin has been shaped by 775 years of world history, but among the countless highlights the city has to offer, the Brandenburg Gate draws the most visitors. As Berlin's only remaining city gate, for decades it symbolized the separation between East and West Germany. When the Berlin Wall was constructed in 1961, the Brandenburg Gate wasn't accessible to commoners. Today, the gate, which was built at the end of the 18th century, is one of the most beautiful examples of German architecture and is easy to visit.
