Cologne Cathedral Introduces Automated Lightning Warning System
Cologne Cathedral has taken a major step in safeguarding its visitors and staff: As the first cathedral in Europe, it has implemented a fully automated lightning warning system designed to detect nearby storm activity and trigger protective measures – especially for the 100-meter-high viewing platform.
Until now, the cathedral’s safety personnel manually monitored weather conditions using services such as the German Weather Service, deciding when to clear the platform. With the new system from Cologne-based company COPTR®, this process becomes automated: real-time lightning data from across Europe is continuously analyzed, and warnings are issued instantly when a storm cell approaches the site.
Discreet Response – Maximum Safety
Visitors already on the platform are allowed to descend safely; entry is restricted during the warning period. Sirens are intentionally avoided – the goal is a calm and orderly evacuation. All warning and all-clear signals are documented automatically in a tamper-proof system, providing full traceability for any future analysis or legal review.
Modern Technology for Cultural Heritage Protection
While no official records of direct lightning strikes on the cathedral exist, the risk is taken seriously. The historic structure has been progressively equipped with lightning protection over the years. The new COPTR® system adds a technical meteorological layer, enhancing overall safety – without requiring structural modifications to the UNESCO World Heritage site.
“This system protects lives,” says Oliver Gassen, Head of Security at Cologne Cathedral. “It gives us objective, real-time information and allows for timely decisions – with minimal disruption to operations.”
