Villa Bianca, Protected mansion on Vassilisis Olgas street, Thessaloniki, Greece

Villa Bianca is a mansion at the corner of Vassilisis Olgas and Themistokli Sofouli streets in Thessaloniki, built 1911–1913 to plans by Italian architect Pietro Arrigoni. It is a characteristic example of the city's eclecticist architecture, with a semi-basement, raised ground floor, one upper floor and a mansard attic. A marble Baroque staircase leads to the main entrance on the east side; there are verandas and balconies on the east and west sides and a secondary entrance on the north.

The building was designed between 1911 and 1913 by Italian architect Piero Arrigoni for a merchant from the Sephardic Jewish community of Thessaloniki. It was built during a period when wealthy families in the city commissioned large private homes along Vassilisis Olgas street.

Inside the villa, visitors can see Byzantine icons, prints, and works by Greek artists displayed across several rooms. The building functions as an art gallery today, giving it a public life that contrasts with its origins as a private family home.

The villa sits on Vassilisis Olgas street, which is easy to reach on foot and lined with other historic buildings worth seeing along the way. It is a good idea to check opening hours before visiting, as the gallery inside may not always be accessible without prior arrangement.

The villa's name honours Blanche de Mayer, the Swiss woman Dino Fernandez Diaz married; his mother had first hired her as a liseuse, a reader of books. The building was also known as Villa Blanche, Villa Bianca and Villa Fernandez. In 1941 the upper floor housed the Italian consul while the Alibertis couple stayed on the ground floor.
