Yourself or with a guide?

Some of the buildings are freely accessible, you can walk through them at your own pace. In most of them tours are organized into groups of different sizes, which will be handled either continuously or at a predetermined hour. The size of the groups is the result of an agreement with the building owners, so please respect this constraint. Only in this way will we succeed in repeated cooperation and we can promise to make buildings available in the years to come.

This year, previous registration is needed only to the technical premises of the Main Point Karlín. The registration will be opened on May 10th at 12 p.m. at our website.

Some tours are guided by our volunteers, some by building owners or managers themselves. Do not expect our volunteers to lead tours with a professional architectural explanation. Their role is to provide you the basic information about the building. However there are professional guided tours led by architects whom we asked to help us within their free time. The information about guided tours are to be found in the Accompanying program section.

The commented tours translated into sign language are the novelty of this years edition. For more information see again the Accompanying program section.

Tailor-made touring circuit

At this festival you are your own guides. You know best what kind of buildings and spaces you are interested in. You can choose from 65 of them, including historic buildings, office buildings and interiors, and also for instance industrial buildings. There are 24 new buildings and spaces in the program. Buildings from the past three years are in the program too, so you have a chance to visit them if you have not managed it yet.

There is a possibility to filter through the program according to various criteria and we have also prepared special thematic tours. During the festival weekend the chat will be available on our website so you can share your tips and experiences with other visitors. Plan your own weekend tour by using the function “My maps” provided by our partner that will be available latest one week before the festival.

When is it open?

Owners of the buildings joined the festival on a voluntary basis. That’s why they decide whether to make their object available for the whole weekend or for just one day. Most of the houses are open from 10 a.m. to 6 p.m. But rather, find the information at the description of each object, because there are exceptions.

Where to find information

Long queues?

The queues are part of the Open House. They are usually not so long that it would be impossible to wait. Take the opportunity and share with your neighbors a series of interesting tips and recommendations on where to go and which building is especially interesting for you. Also, please be considerate for people with reduced mobility or handicap, seniors, pregnant women and mothers with strollers and let them enter the building preferentially.

Where to take the children?

This year, our volunteers will also offer entertaining sheets for small architects at the entrance to selected buildings. For children, there are also festival diaries available that they can fill in during the weekend. Last but not least, we offer special commented tours for children at selected buildings. See the separate section Program for children for more info.

Follow their instructions and keep only in confined spaces. We ask you to behave like a visit, not to threaten the safety of yours or others, and to be considerate. Otherwise, the organizers reserve the right to show you from the building.
