Cologne is the fourth-largest city in Germany - and one of the oldest. A Germanic tribe, the Ubii, had a settlement here, this was named by the Romans "Oppidum Ubiorum". In 50 AD, the Romans founded "Colonia Claudia Ara Agrippinensium", the city then became the provincial capital of "Germania Inferior".

The Ubierring is the southern end of the Cologne Ring ("Kölner Ringe"), a semi-circular, about 6 km long urban boulevard, that encircles the old town of Cologne on the site of the former medieval city wall. The Cologne Ring is very busy four lane street, but here, near the embankment of the Rhine river, the Ubierring is very wide - and has this little park in the middle. A perfect place in spring!
