  Rome constitutes a comune speciale, named "Roma Capitale", and is the largest both in terms of land area and population among the 8,101 comuni of Italy. It is governed by a mayor and a city council. The seat of the comune is the Palazzo Senatorio on the Capitoline Hill, the historic seat of the city government. The local administration in Rome is commonly referred to as "Campidoglio", the Italian name of the hill. Palazzo Senatorio, seat of the municipality of Rome, has been a town hall since AD 1144, making it the oldest town hall in the world.
  
  Since 1972, the city has been divided into administrative areas, called municipi (sing. municipio) (until 2001 named circoscrizioni). They were created for administrative reasons to increase decentralisation in the city. Each municipio is governed by a president and a council of twenty-five members who are elected by its residents every five years. The municipi frequently cross the boundaries of the traditional, non-administrative divisions of the city. The municipi were originally 20, then 19, and in 2013, their number was reduced to 15.
  
  Rome is also divided into differing types of non-administrative units. The historic centre is divided into 22 rioni, all of which are located within the Aurelian Walls except Prati and Borgo. These originate from the 14 regions of Augustan Rome, which evolved in the Middle Ages into the medieval rioni. In the Renaissance, under Pope Sixtus V, they again reached fourteen, and their boundaries were finally defined under Pope Benedict XIV in 1743.
  
  Rome is the principal town of the Metropolitan City of Rome, operative since 1 January 2015. The Metropolitan City replaced the old provincia di Roma, which included the city's metropolitan area and extends further north until Civitavecchia. The Metropolitan City of Rome is the largest by area in Italy. At 5,352 km (2,066 sq mi), its dimensions are comparable to the region of Liguria. Moreover, the city is also the capital of the Lazio region.
  
  Rome is the national capital of Italy and is the seat of the Italian Government. The official residences of the President of the Italian Republic and the Italian Prime Minister, the seats of both houses of the Italian Parliament and that of the Italian Constitutional Court are located in the historic centre. The state ministries are spread out around the city; these include the Ministry of Foreign Affairs, which is located in Palazzo della Farnesina near the Olympic stadium.
