The Rocket War of Vrontados

Every Easter Saturday night on the Greek island of Chios, two rival Orthodox parishes — Agios Markos and Panagia Erithiani — fire an estimated 60,000 homemade rockets at each other's bell towers in a spectacle called Rouketopolemos. The aim is to strike the opposing bell, and both churches invariably claim victory when the smoke clears. The practice traces to the Ottoman era: when imperial authorities confiscated the islanders' cannons in the early 1800s, locals improvised with rockets and never stopped. Steel mesh shields now protect the church windows, and roughly 10,000 spectators attend each year behind safety barriers. Where Easter Witch Bonfires in Finland deploy fire to repel supernatural threats, Rouketopolemos deploys it against an equally real opponent across the street — making it the most combative Easter tradition on this list.
