Kaffee-HAG-Werk I

Kaffee-HAG-Werk I is a factory complex in Bremen-Walle consisting of multiple interconnected buildings made of exposed concrete. The site stretches along the timber square and factory harbor and is used today by various businesses, including a coffee roastery.

Built in 1906 and 1907 by architect Hugo Wagner, the factory revolutionized the industrial production of decaffeinated coffee under Ludwig Roselius. The innovative concrete structures set new standards for factory architecture of that era.

The factory was a place where work and innovation came together. Today visitors can see the raw concrete walls and large windows that define the buildings, telling of a time when factories were designed differently.

The complex is located on Hagstrasse and Fabrikenufer and is easily accessible by public transport. Since most buildings are now occupied by businesses, visitors should view the architecture from outside and enjoy it from publicly accessible streets and squares.

The complex functioned like a small town with its own fire department for safety. The buildings housed up to 19 different companies at various times, all producing related products and closely interconnected within the site.
