Open House is one of the most important global institutions for the promotion of architecture. The idea began at London in 1992 and until today it has spread to many cities around the globe. The Open House project invites the public to explore and understand the value of architecture. Every year for one weekend, private and public buildings open their gates to everyone for free and the city is transformed to a big museum, with its buildings and architecture being the exhibits. Open House in Athens takes place every spring.

The 12th OPEN HOUSE Athens took place on April 5–6, 2025, featuring a variety of events that began a week earlier and attracted tens of thousands of visits! The 13th OPEN HOUSE Athens is scheduled for April 4–5, 2026, with parallel events starting on March 28. We look forward to seeing you!
