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

A city is a human settlement of a notable 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 more narrow sense, a city can be defined as a permanent and densely settled 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 significant negative consequences, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

Hindi is the most widely spoken language in the city.

Prayagraj lies close to Triveni Sangam, the "three-river confluence" of the Ganges, Yamuna, and the mythical Sarasvati. It plays a central role in Hindu scriptures. The city finds its earliest reference as one of the world's oldest known cities in Hindu texts and has been venerated as the holy city of Prayāga in the ancient Vedas. Prayagraj was also known as Kosambi in the late Vedic period, named by the Kuru rulers of Hastinapur, who developed it as their capital. Kosambi was one of the greatest cities in India from the late Vedic period until the end of the Maurya Empire, with occupation continuing until the Gupta Empire. Since then, the city has been a political, cultural and administrative centre of the Doab region. (Full article...)
