Planned city in the context of "Brasília"

The Islamabad–Rawalpindi metropolitan area, commonly referred to as Islamabad–Rawalpindi or the Twin Cities, is the fourth-largest metropolitan area of Pakistan, after Karachi, Lahore, and Faisalabad. With a population of over 5.7 million, it is the third-most populous metropolitan area in the Punjab region, the largest in northern Punjab, and fourth in the entire country. It consists of the twin cities of Islamabad and Rawalpindi; administratively within the Islamabad Capital Territory and the province of Punjab.

The area includes the Pothohar Plateau in northern Punjab, with and the colonial-era city of Rawalpindi, as well as the modern planned city of Islamabad. The region received a major boom with the construction of Islamabad as the capital city of Pakistan in the 1960s.

Islamabad (/ɪzˈlɑːməbæd/ ; Urdu: اسلام‌آباد, romanised: Islāmābād, lit. 'City of Islam', [ɪsˈlɑːmɑːbɑːd] ) is the capital city of Pakistan. It is the country's tenth-most populous city with a population of over 1.1 million, and is federally administered by the Pakistani government as part of the Islamabad Capital Territory. Built as a planned city in the 1960s and established in 1967, it replaced Karachi as Pakistan's national capital. Islamabad is located north of the city of Rawalpindi, with which it forms a metropolitan area of over 5.7 million inhabitants.

The Greek architect Constantinos Apostolou Doxiadis developed Islamabad's master plan, in which he divided it into eight zones; the city comprises administrative, diplomatic enclave, residential areas, educational and industrial sectors, commercial areas, as well as rural and green areas administered by the Islamabad Metropolitan Corporation with support from the Capital Development Authority. Islamabad is known for its parks and forests, including the Margalla Hills National Park and the Shakarparian. It is home to several landmarks, including the country's flagship Faisal Mosque. Other prominent landmarks include the Pakistan Monument and Democracy Square.

Faisalabad, formerly known as Lyallpur, is the second-largest city and primary industrial center of the Pakistani province of Punjab. Located in the Rachna Doab of the central Punjab, it is the third-most populous city in Pakistan. Established in 1890s as a planned city, the population of the city increased six times in the decade following the partition of British India as hundreds of thousands of East Punjabi Muslim immigrants settled the city.

Historically one of the largest villages of Punjab, Lyallpur was one of the first planned cities within British India. It became headquarters of the lower Chenab Colony and in 1898 was incorporated as a municipality. It was restructured into city district status; a devolution promulgated by the 2001 local government ordinance (LGO). The city is the headquarters of the Faisalabad District the total area of which is around 5,856 km (2,261 sq mi) while the urban area controlled by the Faisalabad Development Authority (FDA) is around 1,300 km (500 sq mi).

The Sui dynasty (/swɛɪ/ SWAY) was a Chinese imperial dynasty that ruled from 581 to 618. The re-unification of China proper under the Sui brought the Northern and Southern dynasties era to a close, ending a prolonged period of political division since the War of the Eight Princes. The Sui endeavoured to rebuild the country, re-establishing and reforming many imperial institutions; in so doing, the Sui laid much of the foundation for the subsequent Tang dynasty, who after toppling the Sui would ultimately preside over a new golden age in Chinese history. Often compared to the Qin dynasty (221–206 BC), the Sui likewise unified China after a prolonged period of division, undertook wide-ranging reforms and construction projects to consolidate state power, and collapsed after a brief period.

The dynasty was founded by Yang Jian (Emperor Wen), who had been a member of the military aristocracy that had developed in the northwest during the prolonged period of division. The Sui capital was initially based in Daxing (Chang'an, modern Xi'an), but later moved to Luoyang in 605, which had been re-founded as a planned city. Wen and his successor Emperor Yang undertook various centralising reforms, most notably among them the equal-field system that aimed to reduce economic inequality and improve agricultural productivity, the Five Departments and Six Boards [zh] system, which preceded the Three Departments and Six Ministries system, and the standardisation and re-unification of the coinage. The Sui also encouraged the spread of Buddhism throughout the empire. By the dynasty's mid-point, the state experienced considerable prosperity, enjoying a vast agricultural surplus that supported rapid population growth.

Oscar Ribeiro de Almeida Niemeyer Soares Filho (15 December 1907 – 5 December 2012), known as Oscar Niemeyer (Brazilian Portuguese: [ˈoskaʁ ni.eˈmajeʁ]), was a Brazilian architect considered to be one of the key figures in the development of modern architecture. Niemeyer was best known for his design of civic buildings for Brasília, a planned city that became Brazil's capital in 1960, as well as his collaboration with other architects on the headquarters of the United Nations in New York. His exploration of the aesthetic possibilities of reinforced concrete was highly influential in the late 20th and early 21st centuries.

Both lauded and criticized for being a "sculptor of monuments", Niemeyer was hailed as a great artist and one of the greatest architects of his generation by his supporters. He said his architecture was strongly influenced by Le Corbusier, but in an interview, assured that this "didn't prevent [his] architecture from going in a different direction". Niemeyer was most famous for his use of abstract forms and curves and wrote in his memoirs:

Ciudad de la Paz (Spanish: [θjuˈdad de la ˈpaθ], lit. 'City of Peace'), also known as Djibloho or Oyala, is a city in Equatorial Guinea that is being built to replace Malabo as the national capital. Established as an urban district in Wele-Nzas in 2015, it is now the administrative headquarters of Djibloho, Equatorial Guinea's newest province created in 2017, and is located near the town of Mengomeyén. In 2017, the city was officially renamed Ciudad de la Paz ("City of Peace").

The planned city's location was chosen for its easy access and benign climate. It is notably on the mainland, in contrast to Malabo, which is on the island of Bioko. It was designed by the Portuguese Studio for Architecture and Urbanism FAT – Future Architecture Thinking. It is projected to have around 200,000 inhabitants, a new Parliament building, a number of presidential villas and an area of 8150 hectares. The construction of this new capital has been criticised by the political opposition to President Teodoro Obiang, the driving force behind the initiative. The Government of Equatorial Guinea began to move to the city in early 2017.
