Palazzo Senatorio
The Palazzo Senatorio is the historic seat of Rome’s civic government, rising at the summit of the Capitoline Hill — the most symbolically charged of the city’s seven hills — on the site of the ancient Roman Tabularium and the medieval Senate of Rome. Redesigned to a plan by Michelangelo in the mid-sixteenth century and completed over the following decades, the palace forms the centrepiece of the Piazza del Campidoglio, one of the greatest exercises in Renaissance civic urban design. Today it serves as the official headquarters of the Mayor of Rome and the Rome City Council, maintaining a continuity of civic function stretching back to antiquity.

Overview
The Capitoline Hill — the Capitolium of ancient Rome — was the religious and political heart of the Roman Republic and Empire, home to the great Temple of Jupiter Optimus Maximus and to the Tabularium, the archive of the Roman state. In the medieval period the hill became the seat of Roman civic government, and the Palazzo Senatorio rose on the ruins of the Tabularium. When Pope Paul III commissioned Michelangelo to redesign the entire hilltop for the visit of Holy Roman Emperor Charles V in 1536, the resulting plan — the oval pavement of the piazza, the flanking palaces of the Conservatori and the Nuovo, and the reoriented Palazzo Senatorio — created one of the defining set-pieces of Italian Renaissance urbanism.
History
A civic palace on this site is documented from the twelfth century, when Rome’s communal government — the Senate — established itself on the Capitoline in assertion of the city’s independence from both papal and imperial authority. The medieval building was repeatedly modified, and by the early sixteenth century it had become structurally inadequate and visually incoherent. Michelangelo’s intervention, commissioned by Paul III and realised posthumously by Giacomo della Porta and Girolamo Rainaldi over several decades after the artist’s death in 1564, gave the palace its current double-ramped staircase, the Cordonata leading up from below, and the distinctive twin towers flanking the central block. The bronze Marcus Aurelius equestrian statue — the sole surviving large-scale bronze of an ancient Roman emperor — stood at the centre of the piazza from 1538 until its replacement by a replica in 1981.
What you see
The palace’s exterior is defined by its monumental double staircase leading to the piano nobile, flanked by ancient Egyptian basalt statues of the Nile and the Tiber. The clock tower and twin bell towers above the main block are landmarks visible from much of central Rome. The interior, occupied by active municipal offices, contains rooms decorated in the sixteenth and seventeenth centuries with frescoes of Roman history by artists including Cavalier d’Arpino. The piazza in front — with its geometric star-patterned pavement realised to Michelangelo’s design only in the twentieth century — frames a replica of the Marcus Aurelius equestrian statue, the original of which is housed in the adjacent Capitoline Museums.
Cultural significance
The Piazza del Campidoglio and Palazzo Senatorio rank among the most influential works of Renaissance civic design, studied and imitated across Europe and the Americas from the seventeenth century onward. The continuity of civic government on this hill from antiquity to the present day gives the site a symbolic weight unmatched in Italian urban culture: the Mayor of Rome signs official documents in rooms decorated with paintings of the Senate of the ancient Republic. The Capitoline Hill is at the heart of the Historic Centre of Rome, inscribed on the UNESCO World Heritage List in 1980.
Practical information
Address: Piazza del Campidoglio 1, 00186 Roma. The Palazzo Senatorio is an active government building; the interior is not open to the public. The piazza, the Cordonata ramp, and the exterior are freely accessible at all times. The adjacent Capitoline Museums (Musei Capitolini) are open daily except Mondays and offer access to the Tabularium with its view over the Roman Forum.
Getting there
The Capitoline Hill is a short walk from the Roman Forum and the Colosseum; take metro line B to Colosseo, then walk approximately 10 minutes. Bus lines 40, 64, and several others stop at Piazza Venezia, immediately below the Capitoline. The Cordonata ramp on the northern side of the hill provides gentle pedestrian access from Piazza d’Aracoeli.
