About this quest
The year is 1889 and your name is Mathilde Schleicher — a rising star of the Vienna Opera with a rival who wants to destroy you and a mysterious ally signing their letters simply as freund.
This self-guided walking tour of Vienna takes you through the Innere Stadt, past St. Stephen's Cathedral, the Vienna State Opera, Café Frauenhuber, and the former homes of Mozart, Beethoven, and Sigmund Freud.
Solve coded puzzles, decode ciphered messages, and follow a theatrical story of rivalry, obsession, and secrets through one of Europe's most storied cities. The perfect blend of outdoor escape game, self-guided city walk, and historical discovery.
All you need is your phone. Vienna's music scene is waiting to reveal its darkest secrets.
Is this for you?
Who it's for

Anyone wanting a live guide to quiz about the composers, or not up for 4.1 km on foot over nearly two hours, should choose something else.

A little clarity before you go
Frequently asked questions
Where is St. Stephen's Cathedral, and does the walk start there?
St. Stephen's Cathedral stands in Vienna's Innere Stadt, the old city centre. It is both the starting point and the final stop, so you finish where you began after a loop that takes in the Mozart apartment, the Vienna State Opera and the Hofburg Silver Collection.
How long is the walk and how far will we go?
Plan on around 1.5 to 2 hours for about 4.1 km through the Innere Stadt. There are 12 stops, including Beethoven's Pasqualatihaus, the Sigmund Freud Museum, Zu den fünf Morden, the Albrechtsbrunnen and Café Frauenhuber, with a story and a coded puzzle along the way.
Do we need to book a time or meet a guide?
No. The walk is self-guided and played on your phone, so you can start whenever you like. The app leads you from place to place, tells the story of each stop and sets puzzles based on what is in front of you. There is no group to join and no guide.
Can we play together as a group?
Yes, one ticket covers your whole group, so friends or a couple can follow Mathilde Schleicher's story together and work out the letters from her rival and the mysterious ally who signs as freund side by side.
Is it outdoors, and what if it rains?
It is a walking route through the streets of the old town, so expect to be outside between stops. You can pause the game at any point and continue later, which makes it easy to wait out a shower or take a break.
Is Freud, Beethoven & Mozart: Letters, Keys & Arias self-guided?
Yes. The Questo app guides you between locations without a tour guide or fixed departure. You can start when it suits you and pause if needed.
Where does Freud, Beethoven & Mozart: Letters, Keys & Arias start and finish?
It starts at St. Stephen's Cathedral, Stephansplatz 3, 1010 Wien, Austria and finishes at Museum - Sigmund Freud Museum, Berggasse 19, 1090 Wien, Austria. The route is approximately 4.1 km and includes 12 location-based puzzles.
How many accesses does our group need?

Vienna cultural context
Three famous names who belonged to different Viennas
Mozart, Beethoven and Freud lived and worked in Vienna in different periods and fields: Classical music, Romantic-era composition and the development of psychoanalysis. They did not form one historical circle. This quest brings their legacies together through fictional letters and clues, using real city associations without inventing a meeting among all three men. Playable languages: German, English.
