Mehringplatz 20 is a gallery space located in a bedroom. The space is curated by Magdalena J. Härtelova who also serves as its cleaner, host, and theoretician. Mehringplatz 20 presents solo exhibitions by artists engaged in, as the gallery's Code of Practice states, "thinking and creating postcapitalist worlds". Among presented projects have been: Amy Balkin's (et al.) People's Archive of Sinking and Melting, a documentation of the future of climate change, Bea Xu's Plastic Lattice, a long-distance communication device using period blood and mycelium network, and Alice Yuan Zhang's research on non-Western mutual aid Becoming Infrastructure presented in the form of an exhibition. The gallery also hosts a books, zines, tools, and connections library. When an exhibition is on view, the space is open for walk-ins on Tuesdays from 3pm to 5pm, and by appointment.
