City

A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.

Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process, but it also presents challenges to managing urban growth.

A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis. In terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai.

Origins

There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.

Ancient Siam

Ancient Siam (also known as Ancient City)(Thai: เมืองโบราณ, Mueang Boran) is a park constructed under the patronage of Lek Viriyaphant and spreading over 200 acres (0.81 km²) in the shape of Thailand.

The founder's original idea was to create a golf course with miniatures of Thailand's historically significant structures spread around the course. During his research he found most structures being severely damaged over time and decided instead of creating new miniatures to save the original structures when possible or re-creating them full size or scaled down.

Ancient Siam is dubbed as the world's largest outdoor museum. Situated close to the Crocodile Farm in Samut Prakan province, the 320-hectare city features 116 structures of Thailand's famous monuments and architectural attractions. The grounds of Ancient Siam correspond roughly to the shape of the Kingdom, with each of the monuments lying at their correct places geographically. Some of the buildings are life-size replicas of existing or former sites, while others are scaled down.
