Palazzo Giustiniani, Senate residence near Pantheon, Rome, Italy
Palazzo Giustiniani is a government building near the Pantheon in Rome that now houses administrative offices of the Italian Senate. The stone facade displays a portal with columns and a balcony above, while windows are distributed across three storeys.
Architect Giovanni Fontana began work in 1585 when the Giustiniani family commissioned a new city palace. During the 17th century, Francesco Borromini expanded the building with additional wings and changed the original layout.
The name recalls the Giustiniani family from Genoa, who once owned the property and built their private art collection here. Today the building serves as an extension of the Senate, where officials and staff carry out their duties while the historic halls are used for ceremonial occasions.
An underground passage links the building to Palazzo Madama across the street, where the Senate holds its sessions. Access is only possible on certain occasions and with prior permission, as the building continues to serve political purposes.
President Enrico De Nicola signed the Italian Constitution here on 27 December 1947 in the library. In this room, one of the most important postwar documents was sealed, forming the foundation for today's republic.
