Amidst the cold and damp autumn air of Berlin, deep, ominous bass vibrations seep through the walls of an old East German power plant. Outside, patient night revelers eagerly await, sensing the mystique concealed within. Within these walls lies Berghain, a legendary club in old East Berlin, where techno music dominates, and the boundaries of decadence are relentlessly pushed.

Have you ever wondered how people appear after enduring long nights at Berlin's most renowned club?

Berghain, located near the border between Kreuzberg and Friedrichshain in Berlin, Germany, stands just a short distance from the main line railway station, Berlin Ostbahnhof. In 2007, an American journalist dubbed Berghain as "quite possibly the current world capital of techno," akin to E-Werk or Tresor during their prime days.

For those planning to visit Berlin, especially tourists aspiring to enter this techno temple, here are five best and five worst reviews we've discovered online.

On October 15, 2004, a vibrant crowd filled the old power plant for the first time. The grand hall, which would later transform into the iconic Berghain, was still under construction. Guests congregated in the newly opened Panorama Bar, mirroring the essence of its predecessor. Among the attendees that night was Ostgut regular, Daniel Wang.

"The moment you stepped in, you could feel the uniqueness of this place. The space was awe-inspiring, and the atmosphere, while unpretentious, was brimming with energy," he recalls.

Wang vividly describes the diverse crowd, comprising individuals of various ethnic backgrounds, shapes, and sizes. The attendees included people of different races, yet there were no glamorous celebrities, models, or powerful figures. Everyone present shared a common purpose: to dance, liberated from the need to showcase themselves.

A month after Panorama Bar's inauguration, the steel doors leading to the grand turbine hall swung open, officially unveiling Berghain. The club derived its name from the adjacent neighborhoods, Kreuzberg and Friedrichshain. Much like Ostgut's main floor, Berghain's musical focus gravitated towards dark, hardcore techno that reverberated through the concrete dust.

The dance floor buzzed with enthusiasts, surrendering to the music's rhythm, with the towering ceiling, industrial ambiance, and powerful bass creating a natural force felt far beyond Berlin's city limits.

A legend had come to life.
