Events in a city can have different influences on their architectural framework. An event can happen, then disappear or it can leave traces, leaving reminders of the event, influencing the city long after the event has gone. How do events interpret their architectural framework, how do they affect it and what traces do they leave? This research will focus on events in the city Kassel (DE) and the quinquennial event ‘documenta’. Through drawing, photographs and mapping, this research will explore the traces of past events and their influence of the future of the city. The ‘documenta’ will be seen as a contemporary institution that is currently leaving its traces in Kassel every five years. This research aims to define the appropriation of the architectural framework by events and the traces that they leave behind and how these traces could mean something for the inhabitants.
