Prof. Dr. Koen Ottenheym (UU)

Koen Ottenheym is Professor of Architectural History at Utrecht University. His contribution to the Constructing the Limes project is aimed at the rediscovery of Roman limes by humanists, antiquarians, architects and their clients from the late 15th century to the 18th century along the entire European limes zone along the Rhine and Danube.

The central question is who was interested at that time, and why, for the local ancient past on both sides of the former border. Did they look for the origin of the people, the dynasty or the city in a Roman past or did they prefer to identify with the local ancient population (Batavians, Germans, etc.)? and what different ambitions were associated with these different strategies? And how was that knowledge used in new prestigious construction projects?
