Cities are crisscrossed by a multitude of flows that constantly reorder their material reality. They are organisms whose in/stability depends on a tangle of systems that guarantee certain levels of mobility, food, energy and care. Power plants, distribution lines, sewers, protocols, regulations, antennas, landfills, sensors and purifiers organize the city in a veiled way. This activity proposes a series of guided tours designed to traverse the infrastructural landscape of the city of Madrid.
