Ss. Cyril and Methodius Cathedral
On 18 June 1942, Waffen-SS troops stormed this Baroque church to kill the SOE-trained agents who had just assassinated Reinhard Heydrich.

The crypt holds a museum honoring the SOE-trained Czech and Slovak agents who made their last stand here — two died in the gun battle, the rest by their own hand to avoid capture. The church above, built 1730–1736, still functions as the principal Czech-Slovak Orthodox cathedral.
What to look for
- The crypt museum, dedicated to the agents as national heroes — this is where the final siege actually happened
- The Baroque nave designed by Kilian Ignaz Dientzenhofer, completed 1736, originally built as the Karel Boromejsky Church
- Na Zderaze, the street running alongside, named for a Czech lord killed in 1091 and buried near this site
The crypt museum has a separate entrance from the main church — confirm opening days before you go.

- Prague CastleThe Guinness-record largest ancient castle on Earth — and the Czech president still works inside it.
- Charles BridgeCzech legend holds that Charles IV chose his construction start time — 5:31am on 9 July 1357 — because the digits form a palindrome he believed would imbue the bridge with additional strength.
- St. Vitus CathedralOne theory holds that the founding duke may have chosen St. Vitus partly because his name echoes a Slavic sun god — making conversion easier for a populace already devoted to the solar deity Svantevit. Christian and pagan communities shared this hilltop until at least the 11th century.
