Summary for: Prague is becoming a Netflix thriller, and these landmarks are closing for filmingVisitors hoping to see the Municipal Library’s seemingly endless tower of books will need to postpone their plans this week. Anyone heading for a ride on the newly reopened Petřín funicular next week will encounter a similar obstacle: Prague’s latest starring role for Netflix.
Filming for The Secret of Secrets, the adaptation of Dan Brown’s Prague-set thriller, is closing Mariánské náměstí on Nov. 4–5 and taking the funicular out of passenger service Nov. 10–13. The production stars Morgan Spector as Harvard symbologist Robert Langdon, opposite Rebecca Hall as scientist Katherine Solomon.
FOR OUR MEMBERS
As reported by The Prague Reporter, the shoots are part of an extensive production that has already visited Charles Bridge, the Municipal House and areas in Letná. For residents, that means temporary disruptions. For Prague, it means appearing on screen under its own name, with its landmarks central to the mystery.
What is closed—and how to plan around it
The entire Mariánské náměstí square is inaccessible Wednesday and Thursday, Nov. 4–5, including the main entrance to the Central Library.
The library itself remains accessible through its side entrance on Valentinská Street, beneath the sculpture by Vlado Milunić. However, the popular Idiom book installation, bistro and workshop are unavailable during the closure, according to the Municipal Library’s notice.
Next week, filming moves to another prominent attraction. The Petřín funicular will close from Tuesday, Nov. 10, through Friday, Nov. 13, with passenger service scheduled to resume Saturday, Nov. 14.
According to DPP information reported by The Prague Reporter, the closure concerns the railway. It should not be read as an announcement that all of Petřín Hill’s attractions will close. Visitors planning a trip should check the transport operator’s current information before traveling.
The interruption comes shortly after the funicular returned to service Sept. 22 following a two-year reconstruction. DPP says it carried 413,615 passengers through the end of October, dispatching hundreds of additional journeys to meet demand.
The railway will join a broader selection of familiar sights in the series. DPP transport director Jan Barchánek has confirmed that Prague trams, the metro and Petřín Lookout Tower are also expected to appear.
Prague gets to play Prague
International productions frequently borrow Prague’s architecture to represent somewhere else. The Secret of Secrets offers a different proposition: viewers will follow characters through a city explicitly identified as the Czech capital.
Published in September 2025, Brown’s novel brings Langdon to Prague with Solomon, whose research concerns human consciousness. Her disappearance following a violent incident launches a mystery involving the city’s historic locations before the story extends beyond Czechia.
The book includes Charles Bridge, the Klementinum, Josefov and Petřín’s lookout tower and mirror maze. Mariánské náměstí also appears, giving the current filming restrictions a direct connection to the source material.
The production has already provided glimpses of how that geography will translate to the screen. The Prague Reporter documented early September shoots around Josefov, Jan Palach Square and Čechův most.
A substantial shoot at Municipal House on Sept. 2 closed its restaurant and café. Netflix subsequently released an official production photograph showing Spector and Hall outside the Art Nouveau building, confirming its place in the adaptation.
More recent shoots have visited the surroundings of Letenský zámeček and the Expo 58 pavilion, while Charles Bridge hosted filming in October. Brown has also visited Prague to watch the production at work.
A new Robert Langdon for television
Spector, known for HBO’s The Gilded Age, takes over a character previously played by Tom Hanks in The Da Vinci Code, Angels & Demons and Inferno. Ashley Zukerman portrayed a younger Langdon in the television adaptation of The Lost Symbol.
Hall, Spector’s real-life wife, plays Solomon. The supporting cast includes Cherry Jones, Corey Stoll, Rob Delaney, Abbey Lee, Mamoudou Athie and Anamaria Marinca.
Brown developed the Netflix adaptation with Carlton Cuse, whose credits include Lost, Bates Motel and Tom Clancy’s Jack Ryan. Cuse serves as showrunner and writer, with the series expected to run approximately eight hours. Netflix yet to announce a premiere date.
