Venloer Straße, Cologne Germany

The house with the highest house number in Germany is at Venloer Straße 1501. And even if that is just beyond the Cologne city limits: The “Venloer” is simply ur-Kölsch. In Cologne it begins almost at the cathedral, only the very last section up to the cathedral has a different name. And it leads across the city limits and the administrative district to Kaldenkirchen on the German-Dutch border. As in the vicinity of the cathedral, it is not called Venloer Straße everywhere. Sometimes it’s a shopping street, sometimes a residential street, sometimes a country road, sometimes even a motorway. Venloer Straße is around 8.5 kilometers long in the Cologne city area.

2. Largest mosque

With around 1.08 million inhabitants, Cologne has more than twice as many inhabitants as Malta. In any case, Cologne’s population exceeds that of many countries – such as Iceland (around 339,000 inhabitants), Luxembourg (around 616,000), Montenegro (around 628,000), or Djibouti (around 974,000).

But who knows that the 65-meter high, 17-story tower was the tallest building in Europe shortly after its completion in 1925? It didn’t hold the title for very long, but it remained the tallest “skyscraper” in Germany until 1945.
