Michelangelo’s Design for Piazza del Campidoglio
Despite his opposition to placing the Marcus Aurelius at the center of the Piazza del Campidoglio, Michelangelo’s design for the area is one of the masterpieces of urban planning.  

Michelangelo placed the equestrian sculpture at the center of a slightly mounded pavement, that he embellished with a 12-pointed star.  The 12
points of the star refer to the signs of the zodiac, and the mounding pavement atop which the anicent emperor stands is a reminder of the long-held notion that Rome is the caput mundi, or head of the world.  

Michelangelo’s design for the Campidoglio was constrained by the presence of two late medieval buidlings on the site. There wasn’t sufficient funding
to demolish either the Palazzo dei Senatori at the center of the area, or the Palazzo dei Conservatori on the right.  In answer to these bulidings, Michelangelo constructed a third building on left side, the Palazzo Nuovo.  

Essentially, the arrangement of these buildings created an outdoor room with the Marcus Aurelius at its center.
