Piazza del Campidoglio was designed as a single composition by Michelangelo, and he deliberately turned it away from ancient Rome. He splayed three palaces into a trapezoid, which makes the space look wider than it really is. The entrance ramp climbs from the north-west, so the square faces the papal city and St Peter's rather than the Forum. The oval pavement underfoot carries a twelve-pointed star. The bronze horseman at its centre is a copy; the original stands indoors, in the museum on the right of the square.
When Michelangelo was handed the job the hill held a shabby medieval assembly building and a goat pasture on its slope. He kept the two palaces already standing, added a third to match them, and died without seeing the square finished. The oval pavement you cross was laid four centuries after he drew it, copied from an old print. This is still where Rome is governed: Palazzo Senatorio behind the fountain is the city hall, and Romans say the Campidoglio when they mean the council. There is no gate here, and the square is at its best after dark.
