Cologne in Germany has a long tradition in producing Eau de Cologne and that is where the name "Eau de Cologne" comes from. In former times it was a high class aroma, nowadays Eau de Colognes are cheaper versions of parfums. 4711 Kölnisch Wasser is promoted everywhere, but can`t really compete with good quality parfums.
The picture on the top shows the Dome in Cologne, which is near the main train station (picture below)
There is another church opposite the dome (see picture) and a shopping street nearby. I honestly was not very impressed by Cologne and would not visit it again.
