Villa Celestina, Modernist villa in Castiglioncello, Italy.

Villa Celestina stands at the edge of a pine wood between Castiglioncello's railway station and the sea. Vittorio Cafiero rebuilt it in the early 1930s, stripping away ornament and using reinforced concrete to create an asymmetrical rationalist block with trabeated porticoes and large glazed living areas.

The villa was built in 1932 by architect Vittorio Cafiero, replacing an earlier structure from 1915 on the same site. It initially served as a residence for a high-ranking fascist official before changing its purpose after World War II.

The villa is named after Celestina, Attilio Teruzzi's mother. Until 1943 it hosted numerous parties; after the war it became the seat of the Circolo Villeggianti, with a popular gaming room and a dance hall. From the 1980s it stood abandoned for over two decades.

The villa sits between the railway station and the Mediterranean Sea at the edge of a large pine forest. Its location makes it easily accessible while creating an interesting contrast between the modern building and the coastal natural landscape.

The marine biology centre opened in 2010 under an agreement with the University of Pisa but never ran at full capacity and closed in 2014. In July 2022 the Agenzia del Demanio listed the building for sale, and during 2023 the Spinnato Baldini family bought it to host activities for residents and tourists.
