The landmark of Dortmund is the big U on top of a former brewery building. Today the building houses besides others the Museum Ostwall and some exhibition rooms. The elements looking like mosaics are actually movies shown high over the city.

A fascinating detail of the Zeche Zollern, a colliery in Dortmund: The door at the machine hall is built in the style of Jugendstil (Art Nouveau). Unfortunately it was closed for renovation during my visit.
