Open House Essen returns this September, once again opening doors to buildings that are normally closed to the public. On the festival weekend, everyone is invited to come along, step inside, and gather impressions—whether with a special interest in architecture or simply with the desire to explore their own neighbourhood. What matters most is curiosity about how a city grows and changes.
The 2025 edition of Open House Essen focuses on the theme "Future Heritage: The Legacy of Tomorrow". It explores which buildings and spaces will become the architectural heritage of the future—from historic structures to innovative new projects. As a partner of Open House Europe, the festival raises discussions about what should be preserved and what should be transformed, and how we can shape a liveable and fair future. It encourages reflection on pressing issues such as climate change, democracy, urbanisation, and inclusion.
