Cassiopeia, located at Revaler Str. 99, 10245 Berlin, Germany, is a renowned nightclub and cultural venue that has played a significant role in the nightlife and arts scene of Berlin's Friedrichshain district. Situated on the site of a former railway yard known as RAW-Gelände, Cassiopeia emerged in the mid-2000s as part of a broader transformation of the area into a vibrant hub for alternative culture, music, and subcultures.

The RAW-Gelände itself, with traces of its industrial past, houses a collection of clubs, bars, skateparks, and art spaces, making it a hotspot for both locals and global visitors seeking Berlin's authentic, experimental atmosphere. Cassiopeia is celebrated for its eclectic program that spans electronic music—particularly techno, house, drum and bass, dubstep, and reggae—as well as live concerts featuring punk, rock, hip-hop, and world music. Over time, the club's structure has witnessed several improvements, including renovations to its indoor dancefloors, open-air beer garden, and rooftop terrace, but it has always maintained its gritty, industrial character that echoes Berlin’s post-reunification club culture.

Cassiopeia stands out for its inclusivity and its unwavering commitment to grassroots music and underground artistry, continually providing a platform for emerging talents and local scenes while also attracting international acts. The venue's role extends beyond nightlife—it hosts workshops, skate events, and cultural festivals, reinforcing its reputation as a community-oriented space. While Cassiopeia has retained its original location within the RAW complex since its founding, it has adapted to changing times and tastes, balancing Berlin’s club legacy with new creative impulses.

Notable artists who have performed at Cassiopeia include international acts like The Skatalites, DJ Marky, Pendulum, Black Sun Empire, Talib Kweli, The Slackers, and Dreadzone, as well as respected locals such as DJ Phono, Modeselektor, Paul Kalkbrenner, MC Bomber, and Seeed's affiliated solo projects. The venue often features surprise sets by Berlin’s deep roster of underground DJ talent, further solidifying its place as a cornerstone of the city’s clubbing landscape.
