Begin your Berlin adventure with a visit to one of the city's most famous landmarks: the Brandenburg Gate. The gate was originally built in 1791 to mark the entrance to Unter den Linden boulevard and has since become a symbol of unity and peace. From here, head to the Reichstag Building, which houses the German Parliament. Take a guided tour of the building and enjoy the stunning views of the city from the rooftop terrace.
Next, head to Checkpoint Charlie, the famous crossing point between East and West Berlin during the Cold War. Visit the Checkpoint Charlie Museum to learn about the history of the Berlin Wall and to see artifacts and displays from the period. In the evening, visit Museum Island, a UNESCO World Heritage Site that houses some of the city's top museums and galleries.
Spend your second day exploring the history of the city by visiting the Berlin Wall, a symbol of the Cold War. Visit the Berlin Wall Memorial to learn about the history of the wall and to see a section of the original wall. Then, head to the East Side Gallery, an open-air art gallery that features murals and graffiti art from artists all over the world.
Spend your afternoon visiting some of the city's top attractions. Start with a visit to the Charlottenburg Palace, a stunning baroque palace that was built for Queen Sophie Charlotte. Then, head to the Pergamon Museum, one of the world's greatest archaeological museums that features ancient artifacts and monuments from the Middle East and beyond.
If you have more time, you can consider visiting the Berlin Zoo, the Jewish Museum Berlin, or taking a boat tour on the River Spree. You can also spend some time exploring the trendy neighborhoods of Kreuzberg and Neukölln, which are popular with locals and offer a wide range of bars, restaurants, and street art. If you have less time, you can skip some of the museums or attractions and focus on the must-see sights like the Brandenburg Gate and the Berlin Wall.
