In brief
The value of the historic center is in the connected urban environment, not just in a separate landmark.
Useful to know
Bamberg is an example of how architectural influence can be tracked at the city level. UNESCO links its heyday in the 12th century with an impact on architecture in northern Germany and Hungary. Its earlier history also includes an important connection with the Slavic lands. [1]
In such an object, it is not enough to choose one representative facade. The question is how buildings, streets and open spaces form a coherent environment. Even when viewing individual monuments, their location in the city remains part of the reading.
One approach is to compare a close-up photo with a general urban view. The first shows material and detail, and the second - the relations between volumes. It's a proposed way of observing. The very assessment of historical influence comes from the description of UNESCO, and not from a visual similarity established by only one photograph.
