Brasilia, the capital of Brazil, is one of many capital cities in the world that was designed and built for that exact purpose. The idea that the capital should be moved from Rio de Janeiro to somewhere closer to the country's geographical center was included in Brazil's constitution in 1891, although construction only began in the 1950s, under the lead of newly-elected president, Juscelino Kubitschek. The city was planned out by Brazilian architect Lucio Costa -- who designed a layout in the shape of a plane, or a bird in flight -- with key buildings by famed architect Oscar Niemeyer. Residential areas were organized into "superquadras" ("superblocks"), each designed to function as a self-contained neighborhood. An artificial lake was built, as were as thousands of miles of highway, which facilitated access to the city, but also to the Amazon rainforest, accelerating deforestation. Over time, the city has struggled to adapt to its growth and has split in two, with the affluent center -- closer to the original plan -- now surrounded by a sprawling periphery where poorer people live in far from ideal conditions.

The smallest and southernmost capital city in Europe, Valletta was built after the Great Siege of Malta in 1565. The city was named after Jean de Valette, the victorious Grand Master, and designed by Italian architect Francesco Laparelli, who chose a rectangular grid plan. It was designated a UNESCO World Heritage site in 1980. A new Parliament House was designed by Italian architect Renzo Piano and completed in 2015. Today the city has a population of about 450,000 people.

In 1911, a worldwide competition was launched to design the new Australian capital, and construction began two years later based on the winning plan by American architect Walter Burley Griffin. The plan included geometric motifs and an abundance of green spaces. Capital city status was officially transferred from Melbourne to Canberra in 1927. Canberra has been expanding ever since, although fewer than 400,000 people call it home.

In 1790, the US Congress set aside the District of Columbia for a city that would host the federal government. It was named in honor of President George Washington, who signed the bill into law. The city was planned by French architect Pierre Charles L'Enfant. His work was controversial, and in the early 1900s it was revised by a specially formed committee of architects and planners. The resulting McMillan Plan changed the vision of the city significantly, especially its monuments and parks. A height restriction for all buildings makes Washington unique among large US cities. The Washington Monument is the world's tallest, free-standing masonry structure, at 555 feet or 169 meters.

Before being named the capital of the then British colony Province of Canada in 1857, Ottawa was a small lumbering town. It was selected for its location right on the boundary between the country's French-speaking and English-speaking areas. In 1950 it was significantly updated via the Greber Plan, named after French architect Jacques Greber, who set out to make the city more aesthetically pleasant and responsive to the requirements of a capital. Greber created a greenbelt around the city, while removing the street car system and industrial buildings from the center. The city's Rideau Canal, which connects Ottawa to Lake Ontario, was designated a UNESCO World Heritage site in 2007.

In 1911, King George V, then Emperor of India, declared that the capital of the British Raj -- the UK's rule over the Indian subcontinent that lasted from 1858 to 1947 -- would be moved from Calcutta to Delhi. He laid the foundation stone of New Delhi about three miles south of the center of the existing city of Delhi. The new capital was inaugurated in 1931 and was designed by British architects with wide avenues and grid patterns that were in stark contrast with the narrow and twisting roads of Old Delhi. To this day, the two cities are distinct, with New Delhi -- the capital of independent India since 1947 -- in the south, and the much larger historic city of Old Delhi in the north. The greater metropolitan area is generally called Delhi and is home to over 16 million people.

Islamabad (meaning "city of Islam") replaced Karachi as Pakistan's capital in 1963 after three years of construction. The master plan was designed by Greek architect Constantinos Doxiadis, and the city is divided into eight zones: administrative, commercial, education, industrial, diplomatic, residential, rural and green. With a population of around 1 million people, Islamabad is Pakistan's ninth largest city.

Abuja replaced Lagos as the capital city of Nigeria in 1991. The country had wanted to create a capital city that represented unity and neutrality, and for that reason a location at the center of the country was chosen, with abundant space for expansion and a cooler climate compared to Lagos. Abuja was the fastest growing city in the world between 2000 and 2010, according to the UN, and its metropolitan area is now home to nearly 3 million people. The master plan for the city was created by a team of designers including famed Japanese modernist architect Kenzo Tange.

Gaberones became the capital of Botswana in 1965, one year before the country declared its independence from Britain. The name was changed to Gaborone in 1969. Its design is based on "garden city" principles, which prioritize wide streets and green areas. The city has experienced rapid urbanization in recent decades and now stretches beyond the borders of the city's original plan.

The most recent of planned capital cities is Naypyidaw (also known as Nay Pyi Taw), which replaced Yangon as Myanmar's capital in 2006. For years, the city's large avenues were largely devoid of traffic, and the roads were lined with government buildings, luxury hotels and houses. However, official government data now reports that around 1 million residents live in the metropolitan area.

Lima was founded as the Spanish city of Ciudad de los Reyes ("City of the Kings") in 1535 by Francisco Pizarro, the conquistador who defeated the Inca chief Atahuallpa, leading to the Spanish conquest of Peru. When the Viceroyalty of Peru was established in 1543, Lima was chosen as the capital, as its location on the coast made contact with Spain easier. It remained the nation's capital after Peru obtained independence in the 19th century. The city's historic center was designated a UNESCO site in 1988, and its long history has resulted in a wide range of architectural styles, from Spanish Baroque to Art Nouveau.

The northwest African country of Mauritania chose the small coastal fishing village of Nouakchott to become its new capital, after it gained independence from France in 1960. The choice was mainly due to the town's location between Saint-Louis in Senegal, from where the former French colony was administered, and its then largest city, Nouadhibou. Originally designed to house a population of just 15,000 people, the city has grown into the largest city in the country and now has a population of about 1 million. This growth has been spurred mostly by the displacement of Mauritanians due to droughts and desertification.

Two countries will soon move their capitals to different cities, designed and built exactly for that purpose.

Egypt has been building its new, as-yet-unnamed new capital since 2015, about 28 miles east of Cairo. The government hopes to start operating in the city as early as next year, although the project is facing reported delays.

Indonesia announced similar plans in August, picking a jungle-covered area of eastern Borneo for its new capital, which will replace Jakarta.

The two countries are facing similar problems – both Cairo and Jakarta are overcrowded and congested – but Jakarta is also one of the world’s fastest-sinking cities. It is dropping into the Java Sea due to the over-extraction of its underground water sources, which is causing land subsidence.

Building a capital from scratch, however, is nothing new, and many of today’s world capitals are purpose-built, including Washington DC (United States), Brasilia (Brazil), Ottawa (Canada) and Canberra (Australia).

The practice offers many advantages (and a few risks), starting with the ability to pick a specific location within a country – usually one that sends a message of balance and neutrality.

“The capital is often a compromise,” David Gordon, professor of planning at Queen’s University in Ontario, said in a phone interview. “In the United States’ case, it was a compromise between the rural south and the urban north. And the pick was none of the above, with the Potomac (River) being the boundary between the two.

“The same thing happened in Canada, where the Ottawa River was the boundary between the French-speaking lower Canada and the English-speaking upper Canada. Canberra is partway between Melbourne and Sydney. New Delhi was halfway between Calcutta and Mumbai. And so on.”

According to Gordon, most constructed capitals follow one of three planning models: a grand European-style city with large boulevards, modeled on Paris, which was widely considered to be the most beautiful and best planned city in the 1900s; the so-called “garden city,” born in England and based on self-contained communities surrounded by green areas; and a modernist approach, which came to the fore after World War II and was appealing because it was an international style, helping achieve the neutrality that many planned capitals aimed for, as opposed to local or national styles.

A prime modernist example is Brasilia, planned by architect Lucio Costa, with key buildings by Oscar Niemeyer. “Brasilia is designed as a single piece, because it was commissioned to two men with similar ideas who were able to impose very simple but very robust rules of urban design,” Nuno Pinto, Lecturer in Urban Planning and Urban Design at the University of Manchester, said in a phone interview.

“The city is a UNESCO site specifically to protect its urban design rules, because what is protected is not the architectural components, but the concept of the building and its relation to the surrounding space. You can demolish a building from the 1960s, even if it’s designed by Oscar Niemeyer, as long as you replace it with the same volumes,” said Pinto.

However, Brasilia has arguably failed in its grand aim of becoming an open and egalitarian capital, and is instead marred by social segregation, according to Pinto.

“Brazil has a history of social segregation,” he said. “Lucio Costa, the designer, assumed that he was being equal by guaranteeing that both a judge and a janitor would have a place in the city, but he forgot about the hundred of thousands of people who built the city and were expected to go back to their (home states) but didn’t. And for those people, the city didn’t provide anything.

“They lived in slums. When Brasilia was inaugurated, these people were relocated in just one day. And they were relocated further away, in new metropolitan areas. (The planners) tried to make a more egalitarian city, a fair city, but they failed.”

According to Gordon, it can take time for a capital city to hit its stride, and none deliver in the short term. “The ‘short term’ for a capital city is 50 years,” he said. “Washington was a laughing stock in the 1900s. People said it was a plan without a city. There were huge gaps. The Washington monument was built in the wrong space. It took another hundred years, but now it’s hard not to say that Washington is a success.

“Building a capital city is a very long-term exercise. My advice is to aim high, keep your vision on the long term and stick to the plan.”
