A group of pensioners in Cologne, led by 66-year-old Kalle Gerigk, are staging protests against the city’s housing shortage by demonstrating—and sometimes occupying—vacant properties. The group, dubbed “Mietrebellen” (rental rebels), targets buildings that have remained empty for extended periods. Their demonstrations are often loud and visually striking, frequently drawing a police response. Gerigk and his fellow activists aim to raise awareness about the lack of affordable housing and pressure authorities to take action. The group believes that empty homes should be utilized to address the needs of those seeking accommodation. Their actions represent a growing frustration with the housing situation in Cologne and a direct attempt to challenge the status quo. The protests have garnered media attention, highlighting the issue of vacant properties within the city.
