Longos Mansion

Longos Mansion is a three-story building on Agias Sofias Square in Thessaloniki with red brick walls and Neo-Byzantine decorative elements. The facade displays typical features of this architectural blend, while the ground floor now houses a retail space and the upper floors remain unoccupied.

Architect Leonardo Gennari designed this residence in 1926 for textile industrialist Grigorios Longos. Shortly after its completion, the owner encountered serious financial troubles that marked the building with a story of sudden decline.

The mansion reflects how wealthy industrialists in early 20th century Thessaloniki chose to display their success through architecture. It stands as a record of the building tastes and aspirations of the city's business elite during that period.

The building sits on a busy square in central Thessaloniki and is easy to locate. Since the upper floors are not open to the public, visitors can only view the structure from outside and appreciate its architectural features from the street.

Residents report regular sightings of an elderly couple entering the building at night without using a key. These mysterious encounters have given the mansion a reputation for intrigue and wonder.
