The Basilica of St. Vitus (Münster St. Vitus) is located on the Abteiberg in Mönchengladbach. Together with the town hall and the Church of the Assumption (Kirche St. Mariä Himmelfahrt), it forms the historical centre of the city. Worth seeing is the Bible window from the 13th century in the choir of the church. [German]
The Roman Tower (Römerturm) is one of several towers in Cologne dating back to Roman times. At the time of the Romans the city was called Colonia Claudia Ara Agrippinensium. This was surrounded by a strong wall with a total of 19 towers. Remains of this wall and some towers can still be seen today. [German]
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 detail I was especially impressed in. At the coking plant Hansa I saw a pithead bath. In this hall the workers put their clothes in special frameworks. Each framework is movable up and down by a chain.
Kokerei Hansa is a former coking plant in Dortmund. Today the plant houses a huge climbing gym named Kletterhalle Bergwerk and the remaining installations can be visited by guided tours.
In earlier times German miners used to have a small garden for vegetable and animals behind their homes. While strolling around a mining settlement next to the colliery Zeche Zollern I came across this special breed of chickens. In German they are called Sundheimer.
