Uzbekistan at the 2025 Venice Biennale: Ekaterina Golovatyuk on the Modernist Legacy of a Soviet-Era Solar Furnace
Is it possible to preserve architectural heritage while working towards sustainability? And what to make of the architectural relics of the past century? Can they somehow take on new meaning rather than remaining a representation of dystopias and utopias of the past? All these questions and more are addressed by the Uzbekistan Pavilion at the 2025 Venice Architecture Biennale. Running alternate years with the Art Biennale, this is undoubtedly one of the most important architectural events in the international arena. Promising to be a thought-provoking exploration of Soviet-era scientific ambition, modernist architectural heritage, and the challenges of sustainability in a rapidly changing world, the pavilion hosts the research of GRACE studio - an architectural firm established by Ekaterina Golovatyuk and Giacomo Cantoni - which operates at the intersection of built heritage, contemporary urbanism, and cultural production. Commissioned by the Uzbekistan Art and Culture Development Foundation (ACDF), the pavilion responds to the theme of the Biennale’s curator, Carlo Ratti’s overarching Biennale concept of 'Intelligens'. The pavilion focuses on the Sun Institute of Material Science, originally known as the Sun Heliocomplex, a vast Soviet-era solar furnace built outside Tashkent during the Cold War to test materials at high temperatures. What emerges is the paradox of a structure designed for technological advancement that now faces questions of obsolescence and adaptation in contemporary discourse. TCA spoke with Ekaterina Golovatyuk to understand how the pavilion evolved from years of research into Tashkent’s modernist legacy and why this solar furnace has become the focal point of Uzbekistan’s presence at the Biennale.

Can you tell us how this project began? This is a project commissioned and initiated by Gayane Umerova of the Uzbekistan Art and Culture Development Foundation that works with cultural heritage, museums, and other culture-related initiatives in Uzbekistan but also promotes Uzbekistan’s culture abroad. They have curated large exhibitions in the Louvre, in the British Museum, showing historical artifacts from Uzbekistan, but also art of the 20th century, and Tashkent Modernism is part of their mission in regards to architecture. The Tashkent Modernism XX/XXI project began in 2021, when it became clear that Tashkent had started to change so rapidly that special tools had to be put in place in order to protect the recent architectural heritage that, at the time, was mostly not listed and therefore at risk. Our project team consisted of multiple experts from Uzbekistan and abroad, including a historian, Boris Chukhovich, a team of preservation specialists from Politecnico di Milano led by Davide Del Curto, urbanists Laboratorio Permanente, and an artist [photographer], Armin Linke. For this project, we started by selecting 40 buildings and then narrowed it down to 24, for which we created monographs and statements of significance that described the important values of the building as well as what parts should be absolutely kept and what parts could...
