Palazzo Cattaneo-Adorno, Renaissance palace in Via Garibaldi, Genoa, Italy.

Palazzo Cattaneo-Adorno is a Renaissance palace on Via Garibaldi in Genoa that actually combines two separate residences. Each building maintains its own entrance portal while sharing matching architectural details and ornamentation across the facade.

Cousins Lazzaro and Giacomo Spinola had the palace built between 1583 and 1588 as two symmetrical residences under one roof. In 1609 the western half passed to Filippo Adorno, whose family kept it until the 20th century; the eastern half went from the Saluzzo to the Scassi and then the Cattaneo, giving the building its present name.

The two halves carry different fresco cycles. In the western wing at number 10, Lazzaro Tavarone painted scenes in 1624 celebrating the Adorno family, including Doge Antoniotto Adorno freeing Pope Urban VI at Nocera in 1385 and Guglielmo Embriaco taking Jerusalem. The eastern wing has Giovanni Andrea Ansaldo's Stories of Cupid and Psyche. Rooms also hold 16th- and 17th-century paintings and period furniture.

The palace sits on one of the main streets in Genoa's historic center and is easy to reach on foot. Details about visiting and entry requirements are available through local tourism information.

The building displays an unusual solution where two completely separate palaces share entirely matching facades in perfect symmetry. This approach was uncommon at the time as it elegantly unified two independent noble families under one visual identity.
