How did you become a tour guide?

I worked part-time as a tour guide when I was a student. I did big groups of tourists firsts and then mostly individual clients. Then I moved on to my main job, until I got the opportunity to be a tour guide for one weekend during Open House Prague. It confirmed for me that I still loved doing it, and I felt that I would like to do that more often.

Which building/part of Prague or architectural style is your favorite?

I love the late 19th and early 20th century. It was a time when everything was possible, when historicism competed with progress, and foundations of modernism were being defined. When I see a building from the 1930s that still looks modern today, my heart leaps with joy. It was a time when Otakar Novotný, Josef Chochol, and Emil Králíček tested the limits of where they could go and what they could try. I also like the so-called “ugly architecture” of the 1980s. The courage to work with space and matter differently back then. Architects such as Karel Prager, the Machonins, Alena Šrámková. In addition, I love industrial architecture and its legacy. One of my most powerful experiences was a walking tour of Ostrava’s Lower Vítkovice with architect Josef Pleskot.

How long have you been working with OHP and what do you like about it?

I first volunteered during the festival in 2025 at the Great Strahov Stadium and Hodža Villa. I did two other buildings in 2026 and started doing the year-round walking tours as well. But I had been a regular visitor of the festival’s previous editions, too; always trying to find buildings that aren’t in the spotlight and usually stay forgotten. I’m really happy that such a thing as OHP exists!

What are your hobbies?

I like music, especially the live kind, including contemporary and strange music. Theater, ideally original, unusual, immersive, or interactive. Also science, technology, sci-fi – in any form. But most of all, I like to wander around the city with no direction, look at buildings, and try to figure out what was the author’s or owner’s intention, what it was like to live there in the past, why they chose this and that shape and decoration. How the building came to be right where it is and what’s its role in the context of the location.
