The city of Erbil in Kurdistan has a radial urban structure centred on an ancient fortress.

A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in a world of intensifying globalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, climate change, and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant harmful effects, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

Aerial view of southern Central Park in September 2014

Central Park is an urban park between the Upper West Side and Upper East Side neighborhoods of Manhattan in New York City, and the first landscaped park in the United States. It is the sixth-largest park in the city, containing 843 acres (341 ha), and the most visited urban park in the United States, with an estimated 42 million visitors annually as of 2016. It is also one of the most filmed locations in the world.

The creation of a large park in Manhattan was first proposed in the 1840s, and a 778-acre (315 ha) park approved in 1853. In 1858, landscape architects Frederick Law Olmsted and Calvert Vaux won a design competition for the park with their "Greensward Plan". Construction began in 1857; existing structures, including a majority-Black settlement named Seneca Village, were seized through eminent domain and razed. The park's first areas were opened to the public in late 1858. Additional land at the northern end of Central Park was purchased in 1859, and the park was completed in 1876. After a period of decline in the early 20th century, New York City parks commissioner Robert Moses started a program to clean up Central Park in the 1930s. The Central Park Conservancy, created in 1980 to combat further deterioration in the late 20th century, refurbished many parts of the park starting in the 1980s. (Full article...)

Ebenezer Howard's three magnets diagram, which addressed the question, "Where will the people go?", with three choices being: "Town", "Country", or "Town-Country".

The garden city movement was a 20th century urban planning movement promoting satellite communities surrounding the central city and separated with greenbelts. These Garden Cities would contain proportionate areas of residences, industry, and agriculture. Ebenezer Howard first posited the idea in 1898 as a way to capture the primary benefits of the countryside and the city while avoiding the disadvantages presented by both. In the early 20th century, Letchworth and Welwyn Garden City were built near London according to Howard's concept and many other garden cities inspired by his model have since been built all over the world.
