Berlin—the most famously divided city of the 20th century—has turned into an innovative, design-forward international hub, known for its music festivals and street art as much as for its incredible athletes and modern history. While there is no more Wall, famous landmarks include the Brandenburg Gate, landmark Reichstag (seat of the German parliament), somber Holocaust Memorial, and architecturally diverse Potsdamer Platz. Berlin has more green space than expected, thanks to the presence of Tiergarten, a former royal hunting ground turned massive city park. It's like a forest within the city, bordering the Reichstag and the also-spacious Zoological Garden (home of Knut, the cute baby polar bear). Though its techno and industrial music scenes have claimed much of the spotlight in recent decades, classically sexy cabaret style still exists at the reincarnated Kit Kat Club.
