The Capitoline Hill, between the Forum and the Campus Martius, is one of the most famous and highest of the seven hills of Rome. By the 16th century, Capitolino had become Campidoglio in the Roman dialect. Similarly, the English word capitol derives from Capitoline. The Capitoline contains relatively few ancient ground-level ruins, as they are almost entirely covered up by Medieval palaces (now the Capitoline Museums) that surround a piazza. A significant portion of the architecture in this area was designed by Michelangelo.
