Headed by Nele De Raedt, this group employs analysis and history to study theories and practices of architecture in the late medieval and early modern period (1400-1700). The focus is mainly on the built environment of the city, which the group studies from diverse angles. Using a wide variety of sources (such political poems, ethical treatises, legal contracts, city maps) this group of researchers studies how various actors have shaped (ideas on) the city and its buildings.
