Step inside Ballhaus Berlin. Here, where the doors first opened in 1905 to the dance-loving Berlin public of the Belle Epoque, the spirit of yesterday flows calmly into tomorrow. Wall stucco and spiral staircases, table telephones and chandeliers have been preserved from the building's eventful history. They conjure up a uniquely warm and inspiring atmosphere that is probably unrivalled in Berlin and has been magically attracting nostalgic and curious visitors for decades.
