highest body of the judiciary in the state. Its central court is located in downtown Rio de Janeiro, but, from 2013 to July 2018, some of the courts of this court were moved to Cidade Nova. Federal government The city of Rio de Janeiro was successively the capital of the Portuguese colony of the State of Brazil (1621–1815), after the United Kingdom of Portugal, Brazil and the Algarves (1815–1822), the Empire of Brazil (1822–1889) and from the Republic of the United States of Brazil (1889–1968) until 1960, when the seat of government was definitively transferred to the then newly built Brasília. Despite the change in the federal capital, 59% of civil servants in the Executive Branch of federal agencies and public companies remained in the city. Rio de Janeiro is also the only Brazilian state where the number of federal employees exceeds the number of state employees. About a third of all federal public bodies and companies remain in the former capital, with 50 public offices, including agencies, autarchies, foundations and public companies, such as the National Library, the National Nuclear Energy Commission, Fiocruz, BNDES, Petrobras, Eletrobras, IBGE, Casa da Moeda, the National Archives, among others. Subdivisions The city is commonly divided into the historic center (Centro); the tourist-friendly wealthier South Zone (Zona Sul); the residential less wealthy North Zone (Zona Norte); peripheries in the West Zone (Zona Oeste), among them Santa Cruz, Campo Grande and the wealthy newer Barra da Tijuca district. Rio de Janeiro is administratively divided into 33 distritos (districts) named Regiões Administrativas ("Administrative Regions") and 164 bairros (neighborhoods). Subprefectures are officially grouped into four regions (or "zones"), taking into account geographic position and occupation history; however these do not have any administrative or political power over the municipality. The official political division of the municipality takes into account historical-cultural characteristics to divide the neighborhoods. Most of its population is concentrated in the neighborhoods of Campo Grande, Santa Cruz, Bangu, Tijuca, Realengo, Jacarepaguá, Copacabana, Barra da Tijuca, Maré, Guaratiba and Taquara together, these eleven neighborhoods concentrate a population of 1.5 million inhabitants, according to the 2010 census. Centro or Downtown is the historic core of the city, as well as its financial center. Sites of interest include the Paço Imperial, built during colonial times to serve as a residence for the Portuguese governors of Brazil; many historic churches, such as the Candelária Church (the former cathedral), São
