With a rich history of beer making and a beer (the Dortmunder Bier no less) being brewed in its honour all over the world, in the 1960s Dortmund was, after Milwaukee, the second largest beer-producing city in the world. Much of the city's beer was made in the huge former Union Brewery (know to the locals as the Dortmunder U), which can be see from just about anywhere in the city centre thanks to the huge letter U on the roof. Built in 1927 and empty since 1994, the building is in the early stages of a massive redevelopment programme that plans to transform it into the headquarters for the massive Brau & Brunnen AG brewer as well as office space for other companies. The Richard Rogers design also plans to turn the space inside the famous tower on which the U is located into a combined arts centre and restaurant as part of a larger plan to attract more visitors and investment to the city.
