Explore Prague Through “The Secret of Secrets”: Real-Life Spots From Dan Brown’s Newest Novel

Dan Brown’s The Secret of Secrets, released September 9, 2025, is set in Prague and is among the most anticipated novels of the year, bringing back his signature hero, Harvard symbologist Robert Langdon. In Prague, excitement for the launch was electric, and fans gathered by the Old Town Hall information centre, some reportedly waiting as long as 12 hours to grab one of the first 100 copies signed by Brown.

The story begins with Langdon arriving in Prague for a lecture by noetic scientist Katherine Solomon. Prague provides some of the novel’s most vivid settings, many of which readers can visit today.

What follows is a guide to those real-life landmarks. The descriptions focus only on the places themselves, with no plot details revealed, so fans can explore Prague without encountering any spoilers.

Prague Castle

Prague Castle, often described as the largest ancient castle in the world, is home to several key settings. Katherine Solomon gives her lecture in Vladislav Hall in the Old Royal Palace, a Renaissance chamber once used for indoor jousting. Visitors can also step inside St. Vitus Cathedral, with its soaring nave, gilded pulpit, and the Wenceslas Chapel.

This ornate chamber holds the tomb of Good King Wenceslas and a reinforced metal door with seven locks, guarding the Czech Crown Jewels. Both sites are included with a ticket to the castle’s main visitor circuit.

Four Seasons Hotel

Langdon checks into the city’s Four Seasons Hotel, a five-star property that stretches across four historic buildings. His accommodations are set in the Baroque House, one of the hotel’s most exclusive wings. Fans looking to retrace his stay can book the Royal Suite, a three-bedroom retreat with a bay window and sweeping views of Prague Castle. Rates for the suite start at $7,000 per night in low season.

Charles Bridge

Spanning the Vltava River with its Gothic towers and baroque statues, Charles Bridge is one of Prague’s most iconic landmarks. Robert Langdon experiences the bridge in the quiet before dawn, his footsteps marking fresh snow during an early run.

Old Town Square and Surrounding Streets

Old Town Square, or Staromák, features prominently, along with nearby lanes such as Kaprova and Melantrichova. The area mixes history with lively cafés and bars — from the Týnská Literary Café to Anonymous Bar and Hemingway Bar. Beneath Hotel U Prince, Black Angel’s Bar draws visitors into its Gothic cellar, famous for cocktails and a motto promising: Here Is Impossible Possible.

Petřín Hill

Rising above the city center, Petřín Hill is crowned by its 200-foot tower, built in 1891 as Prague’s answer to the Eiffel Tower. Nearby stands the whimsical Mirror Maze, where angled walls and distorted reflections still entertain. The hill is reached most easily by funicular, though the line is under major reconstruction with new cars expected in 2026.

At the base, the Victims of Communism Memorial depicts bronze figures descending a staircase, each in a further state of decay, symbolizing the suffering and resilience of those persecuted under the regime.

Klementinum Library

Part of a vast Jesuit complex dating to the 1500s, the baroque library at the Klementinum is one of Prague’s most breathtaking interiors. Its gilded balconies, frescoed ceilings, and parquet floors surround more than 20,000 volumes of historic theological works.

The library occasionally hosts rare exhibits, such as the “Devil’s Bible” — the massive Codex Gigas, normally kept in Stockholm. It is described as Langdon’s favorite room in the city, a place of hidden details and architectural puzzles that reward a closer look.

Old-New Synagogue and Old Jewish Cemetery

In the Josefov district, the Old-New Synagogue has stood since the 13th century, making it the oldest active synagogue in Europe. According to tradition, the remains of the Golem created by Rabbi Loew were hidden in its attic.

Just steps away lies the Old Jewish Cemetery, one of the most haunting sites in Prague. More than 12,000 headstones crowd a small plot of land. Visitors often pause at the grave of Rabbi Loew, marked with the symbol of a lion and covered with notes and pebbles left in prayer.

Crucifix Bastion and Folimanka Park

Overlooking Prague from a wooded ridge, the Crucifix Bastion began as a 14th-century fort built under Charles IV and has since been restored after centuries of ruin. In the novel, it houses a private research lab with sweeping views of the city.

Below the ridge lies Folimanka Park, a green space laced with Cold War history. Buried beneath are extensive Soviet-era bunkers, parts of which are still accessible on guided tours. The park also features quirky street art: a ventilation shaft painted as Star Wars’ R2-D2, recently joined by another vent transformed into a Minion.

Wallenstein Garden – Dripstone Wall

One of Prague’s surreal sights, the Dripstone Wall rises over 40 feet in Wallenstein Garden. Built in the 17th century, it mimics a cascade of molten rock, its surface dotted with grotesque faces that visitors often swear shift before their eyes. The wall adjoins the former St. Thomas Monastery, now the Augustine Luxury Hotel, where historic spaces like the monks’ brewery and scriptorium have been preserved.

Where to Eat & Drink

Several of Prague’s cafés and restaurants appear in the novel, offering fans a chance to dine where the characters do. La Boheme Café serves specialty coffee in a chic setting. At the Alchymist Grand Hotel & Spa, a character enjoys the hotel’s famed prosecco breakfast. The courtyard ice rink mentioned in the book was a one-time winter event.

CODA Restaurant is highlighted for refined Czech cuisine in an intimate atmosphere. And beneath Hotel U Prince, Black Angel’s Bar provides a Gothic cellar known for craft cocktails and candlelit intrigue.
