Cologne - Gürzenich

Gürzenich: Medieval guildhall of Cologne

The Gürzenich, a popular and traditional Cologne venue, can look back on a history of over 550 years.  At the same time, the Gürzenich-St. Alban ensemble is one of the city’s outstanding architectural monuments of the 1950s.

Built by the City Council as a civic ballroom and market hall between 1441 and 1447, the Gürzenich was the architectural expression of the prestige of Cologne’s citizens who had recovered their economic strength and gained political power. The festival hall on the upper floor created the distinguished setting for social and political events – this was where Cologne’s guests of honour were received, festivities celebrated by emperors, princes and citizens – but coronations, court sessions and a Reichstag were held also. Since the 1950's it is Cologne's most prestigious congress and festival hall.

Bonn - Rheinische Friedrich-Wilhelms University

Rheinische Friedrich-Wilhelms University Bonn

The Baroque building complex was erected between the end of the 17th and the beginning of the 18th century as a Palatial Residence of the Archbishops and Prince-electors of Cologne. In the south the Residence was adjoined by a quadrangular park called “Hofgarten”, which was adorned with a row of fountains in the middle and flanked by a stream and an alley.

In 1777 the structure burned down and only the wing opposite the garden was rebuilt when, in 1818, the Prussian King Friedrich Wilhelm III – Bonn had become part of his Kingdom a few years earlier – decided to establish a university in Bonn and chose the former Palatial Residence to be the main building. Today the building houses most of the university’s administration and the faculty of humanities of both the Catholic and Protestant religion.
