National Memorial to the Heroes of the Heydrich Terror (Sts. Cyril & Methodius Crypt)
This site is honestly the emotional core. In the crypt of the church where Gabčík, Kubiš, and five others died after a brutal siege, you can still see bullet marks and the confined space where they made their last stand. The museum/exhibit above gives solid context about the operation, the Nazi reprisals (for example Lidice), and the broader terror unleashed after Heydrich’s death. It’s free and really worth the half-hour visit — a solemn, almost sacred experience.
