In 1942, Czech paratroopers were sent into Prague to assassinate Heydrich; afterward, the partisans hid in the crypt of the SS. Cyril and Methodius Cathedral, where they committed suicide rather than be captured by Nazi troops. The intense bravery of the seven paratroopers involved in Heydrich’s death is marked with a permanent exhibition in their memory in the cathedral crypt, which also tells the story of how the Czechs resisted Nazi occupation; displays include maps, period photos, and memorabilia.
Because of this historic episode, the SS. Cyril and Methodius Cathedral is a highlight of World War II-themed tours in Prague, along with sites like the Petschek Palace Gestapo headquarters and Jan Hus Monument. Many bike and driving tours of Prague also stop at the SS. Cyril and Methodius Cathedral, which is located in the New Town.
