The portico links the two wings of the Palace and dates from the first design by Giuseppe Valadier. It is lined by Tuscan columns made of travertine and is closed off by wide glass doors.
The two rooms on either side of the Portico have no decoration and are used now as the Sale Video and Documentazione.
