Firewalls are important today to protect the critical—digital—infrastructure of cities and countries. Once people needed defensive walls of thick stones to deter enemies. The Rondell, built in 1523 in Unterneustadt on the Fulda, was a defensive tower that formed part of the old fortifications of the city. Landgrave Friedrich II had the largest parts of it removed in the eighteenth century. The 15-meter-high domed space, with its nearly 10-meter-thick walls, can only be entered via a floating metal footbridge. Since the year 2000, there has been a beer garden in the Rondell; one room inside the Rondell serves as an exhibition space.

The Hanoi, Vietnam-based filmmaker and artist Nguyen Trinh Thi works with the multi-layered relationships between image, sound, and space. Her documenta fifteen project is based on an autobiographical novel that describes conditions in detention camps. The artist shows scenes in which prisoners go through the forest and harvest chilis to recall home; she combines sound images with memories, landscapes, and stories.
