Finland’s “Aalto Works,” a collection of 13 landmark buildings designed by modernist architects Aino, Elissa and Alvar Aalto, is added to the UNESCO World Heritage List. The announcement, dated July 26, 2026, states that five of the designated buildings are located in Helsinki. The remaining buildings are part of the wider ensemble across Finland, reflecting the architects’ influence through a range of public and institutional works.

UNESCO’s inscription recognizes the collection as a unified heritage property representing the Aaltos’ architectural contributions. The five Helsinki sites included in the listing form part of the broader set of buildings that together constitute “Aalto Works.” The sources describe the property as a group of landmark structures rather than a single building, emphasizing both the number of works and the shared authorship of the Aalto architects.

No additional context such as the specific names of all five Helsinki buildings or the other eight sites beyond the total number is provided in the supplied text, but the sources agree on the UNESCO addition and the Helsinki component.
