Renzo Piano’s Stavros Niarchos Cultural Centre reclaims a former Olympic parking lot in Kallithea by reuniting the site with the sea it once faced. An artificial hill rises gently from the city toward the water, transforming the 170,000-square-meter park into a sloping landscape that culminates in a single building housing the National Library of Greece and the Greek National Opera. At its heart, the open-air Agora acts as a civic spine, connecting the two institutions and inviting the public into a shared cultural realm. Piano’s architecture works through lightness and clarity: a building embedded in the terrain, lifted by a canopy of light, and shaped to restore lost views, creating a new topography where culture, landscape, and the sea converge.
