The historic industrial building of the Hausener Brotfabrik is home to one of Frankfurt's oldest self-managed centers. Here, the non-profit association Kulturprojekt 21 e. V. runs a socio-cultural center with a wide-ranging program of events: every year, around 60 concerts, 100 club nights and numerous other events such as readings, discussions on social issues, lectures and film screenings take place in the large hall of the quaint and charming industrial building.
