In 2025, the OPEN HOUSE ZAGREB FESTIVAL will open with the theme "HERITAGE OF THE FUTURE," which is also the theme of the Open House Europe organization. This theme continues from last year’s festival, which focused on "Revitalizing Architectural Heritage," as the theme "Heritage of the Future" directly connects the past, which is being renewed, with the future of architecture. The semantic fields of the words 'heritage' and 'future' are often opposites: one deals with the past and its resilience, occasionally immobility, and the need to crystallize into material and immaterial memories that fight against the passage of time; the other includes projections and possibilities, something we can imagine, shape, and advance. The first evokes peace, while the second represents constant movement. But what happens when we combine them and think about how these two words—and the concepts, actions, and objects they represent—can connect in various practices related to culture? Our aim through the Open House Zagreb project this year is to explore this dynamic through the criteria for acquiring and conceptualizing the future, as well as through upcoming discourses on architectural thinking about new technologies in heritage practices and activation. This year’s Open House Festival is conceived as a sort of invitation to explore buildings, public spaces, and infrastructure that are often at the center of debates about heritage preservation. But, on the other hand, it is also an invitation to explore contemporary architecture, which will soon itself become heritage, and which we are creating today to leave for future generations. The spaces we shape now point to the ways in which future generations will understand their history and identity. These spaces preserve our collective memories and stories, which increases our responsibility to highlight valuable architectural heritage and preserve its integrity, as well as to recognize what we will be remembered for in the future.
