Ympyrätalo, Protected office building in Siltasaari, Finland.
The circular structure of Ympyrätalo stands as a defining architectural element in Helsinki's skyline, featuring a continuous curved exterior wall of windows and concrete.
Completed in 1968 by architects Heikki and Kaija Siren, Ympyrätalo replaced several wooden houses and stone buildings, including the 1903 Wendt House by Gustaf Estlander.
The building represents Finnish architectural innovation of the 1960s through its round shape and functional design, setting it apart from conventional office structures of that period.
The building houses multiple services including a medical clinic, grocery store, pharmacy, and liquor store, with direct access to Hakaniemi metro station and tram connections.
A minimalist steel ball sculpture called The Symbol, created by Hannu Siren, son of the original architects, has stood outside the building since 1985.
