Berlin’s "Tunnel of Horror" to be reborn as a lively hub after years of neglect
The ICC underpass in Berlin’s Charlottenburg-Wilmersdorf district, long infamous as the "Tunnel of Horror" for its decaying infrastructure, foul odours and piles of rubbish, is to be transformed into a daily leisure destination under plans agreed by the local borough and civic partners. From next month, the 200-metre concrete tube will host a pop-up bistro, outdoor fitness classes and community events, in a bid to reverse years of urban decay.
The decision follows a year-long campaign by residents and local councillors who documented broken lighting, overflowing bins and persistent stench from backed-up sewers. “The tunnel had become a magnet for drug use and dumping,” said district councillor Klaus Mindrup. “We needed to act before the situation became irreversible.” District authorities have now earmarked €180,000 for immediate repairs to ventilation and drainage, while a private café operator will run the bistro under a six-month pilot.
Neighbourhood groups welcomed the initiative but warned that long-term success hinges on round-the-clock security and regular cleaning. “We’ve seen similar projects fail when the novelty wears off,” cautioned local resident Fatima Özdemir. “The borough must commit to daily patrols and transparent waste management.” The council has pledged to install 12 new CCTV cameras and a 24-hour hotline for complaints.
The ICC underpass has been a flashpoint since its construction in the 1970s. Once a key pedestrian route to the International Congress Centre, it fell into disuse after the fall of the Berlin Wall and became a byword for urban blight. A 2024 survey by the district found 78 per cent of passers-by avoided the tunnel after dark, citing safety concerns.
Berlin is not alone in confronting derelict infrastructure. In Helsinki, authorities have begun emergency repairs to a landmark building after reports of possible asphyxiation risks in its basement . Meanwhile, Vienna’s public transport network faces its busiest summer of closures, with the U4 line shut for modernisation until September .
For Berlin’s ICC tunnel, the immediate priority is to restore basic functionality. “We’re starting with small steps,” said Mindrup. “If the bistro and fitness classes draw people back during daylight hours, we can justify further investment.” The pilot is scheduled to run until November, with a decision on permanent use to follow.
