In brief
The palaces are only part of an environment with religious and public functions.
Useful to know
Fasil Ghebbi in Gondar, Ethiopia, is a fortified imperial ensemble associated with the 16th-XVII century. It includes palaces, churches, monasteries and other public and private buildings. UNESCO describes a variety of cultural influences in its architecture. [1]
Consider the complex as a group, not as a castle. Compare the size and location of the buildings and how the fortified border unites them. When recognizing an external influence, the similarity of a tower is not enough. It is more reliable to trace the documented construction periods and specific forms without inventing the origin of every detail.
