The Venice square is located in the geographical center of the city. The square is named after Palazzo Venezia, one of the first Renaissance palaces in Rome. It was originally built by Pope Paul II and used to be the seat of the Republic of Venice. During the 20. century Mussolini used it as his office from where he delivered many of his famous speeches to the crowd. Basilica San Marco one of the oldest churches in Rome is located within the walls of the Palace of Venice, originally built in 336 AD by Pope Mark as a national church for Venice. During recent excavations for the new metro line remains of the emperor Hadrian’s Athenaeum were discovered in the square.
