Palazzo Sciarra Colonna di Carbognano, Palace in the Colonna district, Rome, Italy

Palazzo Sciarra Colonna di Carbognano is a Renaissance palace in the Colonna district featuring a monumental facade on Via del Corso. The entrance is framed by two fluted columns that support a first-floor balcony with dressed ashlar stonework.

The building was created in 1610 by merging two separate structures under architect Flaminio Ponzio's direction for the Colonna di Sciarra family. This combination produced a unified palace along one of Rome's major thoroughfares.

The interior walls display frescoes by Giuseppe Cellini that show women's virtues through everyday scenes rendered in the Art Nouveau style. This artistic decoration shapes how visitors experience the rooms today.

The building now houses the Rome Foundation headquarters at Via del Corso 239 in central Rome's location. Its position near the Trevi Fountain makes it easily accessible by public transportation.

The portal, known as the portal of Carboniani, was long believed by Romans to be carved from a single block of marble, one of the four wonders of Rome. Its author is still uncertain; the most credited attribution is to Antonio Labacco or an architect in the circle of Antonio da Sangallo the Younger, since Flaminio Ponzio only reached Rome in 1585.
