Architecture is a part of our daily lives, and Open House Prague invites you to explore it in an unconventional way! The mission of the festival is to awaken people’s interest in public space and architecture. Open House Prague provides a direct experience of architecture through tours of buildings and spaces that are usually inaccessible, allowing you to get to know it in various contexts.

As part of the Open House festival, we are opening three buildings to the public throughout the festival weekend.

At Brumlovka in Prague 4 (guided tours up to the rooftop terrace)

Delta Building: Za Brumlovkou 1559/5, Prague 4
Filadelfie Building: Želetavská 1525/1, Prague 4

At Roztyly in Prague 4 (guided tours up to the rooftop terrace)

Roztyly Plaza Building: Tomíčkova 2427/2, Prague 4

Detailed information and details about visiting individual buildings can be found on the official website of the Open House 2026 festival.

We look forward to your visit.
