Open House Praha, z. ú.

Philanthropy and Volunteering Culture, Art and History

Support the festival Open House Praha and also whole year activities!

We offer extraordinary experiences and fulfill childhood dreams! Thanks to the Open House Prague festival, you can freely peek into dozens of normally inaccessible buildings and spaces during one weekend in May. We open the city to all who want to listen to the stories of buildings they pass by every day. We engage children in the festival through interactive tours and workshops. As one of the few festivals in the Czech Republic, we also prepare special programs for people with disabilities. Behind this unique experience are demanding year-round preparations and associated financial costs. Without the support of donors and partners, and without the invaluable help of hundreds of volunteers, we wouldn't be able to make it happen.

Are you passionate admirers of the beauty of Prague? We offer you a unique opportunity to explore the city from a different perspective! Only with us, once a year, you can freely enter buildings that are otherwise inaccessible.

Did you enjoy our activities? Did you have a good time at the festival? Support us in our efforts to open the city to everyone and provide the opportunity not only for yourself but also for people with visual or hearing impairments, seniors, or families with children to explore their city. One of the rules of the international license for organizing the festival in Prague is free entry to open buildings.

Your donations will provide essential support not only for the preparation of the festival but also for other interesting tours and events throughout the year, including those for our fantastic volunteers. You can send an individual donation of any amount or join regular supporters in the Architecture Lovers Club.

About Us

We are enthusiasts who love Prague. We want to bring you unique experiences in exploring its fascinating architecture. Inspired by the idea of opening normally inaccessible buildings to the public, which originated in London in 1992, we decided to bring the festival to Prague in 2014 and founded the non-profit organization Open House Prague. A year later, we hosted the first edition of the eponymous festival, which will celebrate its 10th anniversary this year. Find out more about us on
