Practical information

When is it open?

Owners of the buildings joined the festival on a voluntary basis. That’s why they decide whether they want to make their premises available for the whole weekend or just for one day. Most buildings will be open from 10 a.m. to 6 p.m. Yet, we recommend that you check out the exact time at the description of each building because there may be exceptions.

Is registration for the festival required?

You don’t have to register to visit our buildings. However, some accompanying activities starting on September 1st, 2020 may require an advance registration.

Can I enter buildings freely, or only with a guide?

Some of the buildings are freely accessible and you can walk through them at your own pace. In most buildings, however, tours are organized into groups of different sizes, which will be handled either continuously or at a predetermined hour. The size of the groups depends on the agreement with the building owners. Please respect this constraint so we can successfully and repeatedly cooperate with the buildings in the years to come.

Some tours are guided by our volunteers, some by building owners or managers themselves. Please, be aware of the fact that our volunteers are not professional architects, but they have been provided with several training sessions and learnt a lot of information about particular buildings from their own sources.

Are there any tours in English?

There are five buildings that offer English tours: The Disk Theater, Na Zábradlí Theater, House on Sněmovní 7, Church of st. Anna, City Mayor’s Residency  (a special icon in the guide as well as on the website will inform you about them). There are also others which you can visit freely without a guide. Most of our volunteers speak English, so feel free to ask them for some basic information or for a fact sheet in English if available.

Are there any recommended city tours?

At this festival, you are your own guides as you know best what kind of buildings and spaces you are interested in. Our printed guide contains a special selection of buildings and premises you can visit. Most of these buildings are located within walking distance, offer tours in English or you can visit them freely without a guide.

Where to find information?

From September 1st, you can find us at the festival infopoint at the Radost House (nám. Winstona Churchilla 1800/2, Prague 3) on workdays from 10 a.m. to 6. p.m. and at the weekend from 9 a.m. to 7 p.m. We will be happy to answer your questions.

There you can also buy our printed festival guide. The guide is available in Czech, but this year it contains a special English section. You can pre-order the guide in our E-shop.

Complete information can be found on our website

The English information about every building is available during the festival weekend online at or in a relevant mobile app (download here for free). Via the map app you can even plan your own route. During the weekend the festival interactive chat is available on the Czech version of our website, too.

In case any questions arise please do not hesitate to ask our volunteers – they will be wearing festival color t-shirts.

Where can I buy festival souvenirs?

From September 1st, all souvenirs can be bought at the festival information point at the Radost House. Selected souvenirs, including the printed guide, can be bought also at these buildings: Palace of Culture – Congress Center Prague, Stock Steam Mill (Classic 7 Business Park) – offices of Etnetera, Kovařovic Villa, Desfours Palace, Water Tower in Letná, General Pension Institute – Radost House, Vlna Community Center, Quadrio.

Where to take children?

During the festival weekend a Lego open workshop will be prepared at our information point. Together with your kids, you can also collect stickers relating to selected buildings. We offer also some special tours for children, but they are only in Czech. See the programs for children here.

Where can I enter?

In each building, you will be welcomed by our volunteers and co-workers who will take you through the accessible parts of the building and answer your questions. Follow their instructions and keep only within the spaces available for visitors. We ask you to be considerate and to behave like you would at any other visit and not to endanger other people’s or your personal safety. Otherwise, the organizers reserve the right to escort any individual from the given building. Please note that the entry to the rooftops and other normally inaccessible spaces will be at your own risk.

How much does it cost?

The entry to all buildings is free of charge. However, it is only thanks to your support that we are able to work on the festival’s organization throughout the year. Please be so kind and help us make another year of the festival happen by purchasing our festival guide and many other materials that we have prepared for you this year (t-shirts, festival diary, bags, coloured pencils, badges, posters, stickers, etc).

If you like the festival, you can also support us financially through the payment gateway Our regular contributors can become members of our Club of Architecture Lovers.

Your support is a feedback telling us that our work has not been in vain and that you care for the festival and are interested in other Open House activities planned throughout the year. Thank you for being with us!

Are dogs allowed on tours?

We kindly ask you that you do not take your pets inside the buildings. This does not apply to assistance dogs and guide dogs who accompany people with disabilities.


During the festival and its accompanying events, we take photos and audiovisual recordings which we then use on our website, social media, and in the annual report of Open House Prague which serves to inform about events, to promote, and to give a report about our activity. If you don’t wish to be photographed, please inform our photographer during the festival (he wears a sticker that says “FOTOGRAF” – “photographer”), or reach out to us via e-mail ( You can read about our protection of personal data here.
