Target group: participants in the excursion to Turin, Italy. The research module is concerned with the implementation of geometry in architecture with the help of brick modules. There are three steps which characterize our activities from practical experimentation to theoretical discourse: First, the layouts characteristic of Turin Baroque are broken down into brick modules. Subsequently, during the excursion, real-world examples can be examined on site. Finally, the impressions of brick as a building material will be described in written form.
