The streets between Piazza Venezia
, Piazza del Campidoglio
and Via delle Botteghe Oscure lead to Piazza Margana or Piazza Marghane, the square named after the powerful family that lived in the district. This medieval area was not touched during modifications to Rome made in the 19th and 20th Centuries. The palaces of the nobility were all built in the 17th Century over Renaissance buildings so they have maintained their original characteristics. The Palazzo Albertoni was frequented by artists and writers who instituted the monthly prize, the Tor Margana, which lasted until the 1970s. The square was also used for open-air art exhibitions during those years.
