Prague, like a well-kept puzzle box, clicks open the moment you drop The Secret of Secrets on your lap. Streets that once served emperors, alchemists and astronomers now play bit parts in Dan Brown’s newest Langdon caper — and if you’re the sort of traveller who likes your sightseeing with a side of cryptography, Prague is offering guided spoilers.
Perched high above the Vltava River, Prague Castle is the city’s most commanding landmark and one of the largest castle complexes in the world. It has been the seat of Czech rulers for over a thousand years and today serves as the official residence of the president. Inside the Old Royal Palace, the vast Vladislav Hall with its late-gothic ribbed vaulting was once the setting for coronations and royal banquets. St Vitus Cathedral within the castle grounds holds the tombs of Bohemian kings and holy relics, and its stained-glass windows cast a kaleidoscope of colour across the nave.
Visiting tips: The castle grounds open early, but access to interiors such as the Old Royal Palace and cathedral require a ticket. Arrive in the morning to avoid queues, and allow at least half a day to explore the full complex.
Once a Jesuit college, the Klementinum is a sprawling complex known for its exquisite Baroque Library Hall. With frescoed ceilings, antique globes, and oak shelves stacked with centuries-old volumes, it feels like treading into a hidden chapter of European history. The Astronomical Tower offers sweeping views over Prague’s skyline, and the Meridian Hall recalls its use in astronomical measurements.
Visiting tips: The Klementinum can only be seen on guided tours, which usually include the library, Meridian Hall, and the tower. Tours are timed, so it’s best to book in advance. Photography is limited inside the library.
Built in the 14th century under Emperor Charles IV, Charles Bridge is Prague’s gothic artery across the Vltava River. The bridge is lined with thirty baroque statues, most of them replicas of originals now housed in museums. Guard towers at both ends—the Old Town Bridge Tower and the Lesser Town Bridge Tower—offer views of the city framed by the river and castle.
Visiting tips: The bridge is open at all hours. Visit at sunrise for near-empty views and magical light, or at dusk when the city glows but expect heavier crowds. Street performers and artists add to the atmosphere throughout the day.
The Old Town Square has been Prague’s beating heart since the Middle Ages. It is surrounded by pastel-coloured gothic and baroque houses, the Church of Our Lady before Týn with its twin spires, and the medieval Astronomical Clock mounted on the Old Town Hall. The clock, or Orloj, has been marking time since 1410, with hourly shows featuring animated apostles and symbolic figures.
Visiting tips: The Astronomical Clock draws large crowds, so arrive early for a good view or step back into side streets for breathing room. Climbing the Old Town Hall Tower offers panoramic views of the square and rooftops.
Petřín Hill is a green escape west of the city centre, accessible by funicular. At its summit stands the Petřín Lookout Tower, a miniature cousin of the Eiffel Tower built in 1891. The hill also houses the Mirror Maze, landscaped gardens, and quiet wooded paths that contrast with Prague’s dense old streets.
Visiting tips: Take the funicular up and walk down through gardens to enjoy both convenience and scenery. The Petřín Tower requires a small entrance fee and a climb up spiral stairs, but the panoramic view over red rooftops and spires is unmatched.
Located in the Josefov quarter, the Old-New Synagogue is Europe’s oldest active synagogue, dating back to the 13th century. Its gothic interior is spare and solemn, a living monument to Prague’s Jewish heritage. The Old Jewish Cemetery nearby is one of the most evocative sights in the city: thousands of gravestones are packed tightly together, layered over centuries due to limited burial space.
This district is also tied to the legend of Rabbi Judah Loew and the Golem, a clay figure said to be animated to protect Prague’s Jews.
Visiting tips: The synagogue and cemetery are part of the Jewish Museum complex and require tickets. Photography may be restricted inside. Visit early in the day for a quieter, more contemplative experience.
Built in the early 17th century as part of Albrecht von Wallenstein’s palace, the Wallenstein Garden is a serene baroque retreat with geometric hedges, fountains, and mythological statues. The highlight is the artificial dripstone wall, whose grotto-like façade hides grotesque shapes and figures. Peacocks often roam the grounds, adding a surreal note.
Visiting tips: The garden is free to enter and usually open from spring through early autumn. It provides a peaceful pause between major attractions.
Lesser known to tourists, Folimanka Park spreads beneath the old city walls on Prague’s south side. Its Crucifix Bastion is one of several preserved sections of the medieval fortifications. Today the park offers leafy paths, playgrounds, and quiet vantage points over the city.
Visiting tips: Open year-round and free to access, the park is best for travellers who want to escape the busy historic core while still touching authentic fragments of the city’s defenses.
Beyond Prague, two Czech towns extend the themes of history and mystery. Český Krumlov, a UNESCO site on the Vltava River, is famed for its fairytale castle, winding alleys, and Renaissance charm. Kutná Hora, once a silver mining hub, holds the gothic St Barbara’s Church and the eerie Sedlec Ossuary, decorated with human bones.
Visiting tips: Both towns are reachable as day trips from Prague. Trains and buses connect regularly, or guided excursions offer added context. Kutná Hora’s ossuary is small and best seen outside peak hours.
Prague has always invited interpretation—as a medieval capital, a Renaissance hub, a stage for revolution, and now as the scene of Brown’s fictional codes and conspiracies. The city’s layered architecture and legends make it the perfect stage for literary tourism. “Dan Brown’s novel shines a spotlight on Prague in a way that blends storytelling with travel,” said Barbara Andelová, international marketing manager, New Markets, CzechTourism. “It offers readers and visitors a chance to rediscover the city through mystery and imagination, adding a fresh dimension to how Prague can be experienced.” Following Langdon’s trail is not just about fandom; it’s about learning to see Prague as a living manuscript, one that rewards curiosity, patience, and imagination.
