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.

Recognised as the capital of Scotland since at least the 15th century, Edinburgh is the seat of the Scottish Government, the Scottish Parliament, the highest courts in Scotland, and the Palace of Holyroodhouse, the official residence of the British monarch in Scotland. It is also the annual venue of the General Assembly of the Church of Scotland. The city has long been a centre of education, particularly in the fields of medicine, Scottish law, literature, philosophy, the sciences and engineering. The University of Edinburgh, founded in 1582 and now one of three in the city, is considered one of the best research institutions in the world. It is the second-largest financial centre in the United Kingdom, the fourth largest in Europe, and the thirteenth largest internationally. (Full article...)

Hong Kong is a special administrative region of the People's Republic of China. With 7.4 million residents of various nationalities in a 1,104-square-kilometre (426 sq mi) territory, Hong Kong is one of the most densely populated territories in the world.

Hong Kong was established as a colony of the British Empire after the Qing dynasty ceded Hong Kong Island in 1841–1842 as a consequence of losing the First Opium War. The colony expanded to the Kowloon Peninsula in 1860 and was further extended when the United Kingdom obtained a 99-year lease of the New Territories in 1898. Hong Kong was occupied by Japan from 1941 to 1945 during World War II. The territory was handed over from the United Kingdom to China in 1997. Hong Kong maintains separate governing and economic systems from that of mainland China under the principle of one country, two systems. (Full article...)

Plymouth, Montserrat, is the only ghost town that is the capital of a modern political territory. It was rendered uninhabitable and evacuated in 1995 after being inundated with volcanic ash from the eruption of the Soufrière Hills Volcano.

A ghost town, deserted city, extinct town, or abandoned city is an abandoned settlement, usually one that contains substantial visible remaining buildings and infrastructure such as roads. A town often becomes a ghost town because the economic activity that supported it (usually industrial or agricultural) has failed or ended for any reason (e.g. a host ore deposit exhausted by mining). The town may also have declined because of natural or human-caused disasters such as floods, prolonged droughts, extreme heat or extreme cold, government actions, uncontrolled lawlessness, war, pollution, or nuclear and radiation accidents and incidents. The term can sometimes refer to cities, towns, and neighborhoods that, though still populated, are significantly less so than in past years; for example, those affected by high levels of unemployment and dereliction.

Some ghost towns, especially those that preserve period-specific architecture, have become tourist attractions. Some examples are Bannack, Montana in the United States; Barkerville, British Columbia in Canada; Craco and Pompeii in Italy; Aghdam in Azerbaijan; Kolmanskop in Namibia; Pripyat and Chernobyl in Ukraine; Dhanushkodi in India; Fordlândia in Brazil and Villa Epecuén in Argentina.
