Marmorsaal, Event hall in the Überseestadt, Bremen, Germany

The Marmorsaal is a hall on the ground floor of a storage extension of the former Kaffee-HAG Works I on Hagstraße, about 30 metres long and 15 metres wide. Its walls are clad in Italian Carrara marble, and dark wooden Art Nouveau display cases are set into one wall, now holding original packaging, advertising signs and porcelain. Decorative opaque windows on two sides carry the coats of arms of Saxony, Brandenburg, East Prussia, Lower Silesia and Bremen.

Ludwig Roselius, founder of a major coffee company and inventor of decaffeinated coffee, commissioned the hall's construction in 1914 as part of his factory complex. The building reflected the prosperity and industrial success of the company during that period.

The hall contains original display cases with historic coffee packaging, signage, and porcelain pieces that document the company's development across generations. These objects show the craftsmanship and design traditions connected to the factory's operations.

The space accommodates up to 80 people and includes modern audio-visual equipment for events. Visitors should remember this is a protected heritage site where respecting the historic surroundings is important.

The hall served as an exclusive dining room for owner Ludwig Roselius and his roughly 40 directors; other staff saw it only at company anniversaries, while the workers' canteen lay in the basement below. After the 1979 sale to General Foods it stood mostly empty and was closed in 1991.
