The charming medieval coopers' lane was transformed into a prime example of mostly expressionist architecture in the 1920s at the instigation of coffee merchant Ludwig Roselius. Its red-brick houses sport unique facades, whimsical fountains, statues and a carillon; many house artesanal shops and art museums. Its most striking feature is Bernhard Hoetger's golden Lichtbringer (Bringer of Light) relief that keeps an eye on the north entrance.
