towards the visual focus by the Palazzo Senatorio. For this purpose, Michelangelo had the idea of building a new building, Palazzo Nuovo, to close off the perspective towards the basilica of Santa Maria in Ara Coeli and to pave the square. Palazzo dei Conservatori The Palazzo dei Conservatori (English: Palace of the Conservatories) was built in 1453, when Pope Nicholas V, had Italian sculptor and architect Bernardo Rossellino build the palazzo on top of a sixth-century Temple of Jupiter Optimus Maximus, to create the headquarters for the local magistrates, named Conservatore of Rome. Today, portions of the temple podium and foundations can be seen behind the Palazzo dei Conservatori, in an exhibition area built in the Caffarelli Garden, and within the Capitoline Museums. A part of the eastern corner is also visible in the via del Tempio di Giove. The front porch of the Palazzo dei Conservatori sheltered offices of various guilds. Here disputes arising in the transaction of business were adjudicated, unless they were of sufficient importance to go before a communal tribunal, such as that of the conservatori. It was a natural place for such activity. Until the 1470s the main market of the city was held on and around the Campidoglio, while cattle continued to be taxed and sold in the ancient forum located just to the south. Rossellino built a building with a round arched portico on the ground floor and a façade with cross windows and paired loggias. The orientation of the pre-existing structures was preserved according to a design principle identical to the one that Rossellino implemented subsequently in the town of Pienza, creating a trapezoidal square. The renovation also involved the Palazzo Senatorio, but were interrupted by the death of the pope. The Capitoline Wolf sculpture was housed in 1471 in the Palazzo dei Conservatori. The 15th-century Palazzo dei Conservatori, at the Capitoline Museums, was almost demolished in 1540 by Michelangelo, but the fifteenth-century design was documented in the drawings by the Dutch painter Maarten van Heemskerck made between 1536 and 1538. He redesigned the Palazzo dei Conservatori, removing all the previous structures and matching it with the Palazzo Senatorio. He added a double stairway which was used to access the new entrance, no longer facing the forums but towards the square. He also modified the façade, in order to bring it into line with that of the Palazzo dei Conservatori and that
