In brief
The building and the statue of Roland form an ensemble in which the civil authority receives a visible image.
Useful to know
The town hall of Bremen was built at the beginning of the 15th century in Gothic style and renovated at the beginning of the 17th century in the spirit of the Weser Renaissance. Next to it stands the statue of Roland from 1404. UNESCO considers the ensemble in relation to the city's civic autonomy and commercial history. [1]
Changing the facade language does not necessarily mean replacing the whole building. It is the combination of an early core and later a representative layout that makes the town hall interesting to read on building layers.
On a general view, include the space around the statue. Sculpture is not just a separate subject in front of a facade, but part of the way the ensemble is perceived. If you're comparing dates, name whether it's the first town hall, its makeover, or the newer additions, instead of choosing a year for everything.
