Europe, however, had no room for utopias: the continent already boasted its fair share of cities and constructions. More adventurous spirits therefore turned their attentions to the terra incognita of the New World in a bid to see through their dream projects. Driven by their religious convictions, they set their sights on a new, perfectly organized city.
Philadelphia, also known as the "city of brotherly love", was founded in 1680 and was the archetypal American city. Turning their backs on the centrist model with its seat of government as the hub, the newcomers dreamed of an egalitarian lifestyle (at least as far as the colonists were concerned) where people could enjoy freedom of worship. They chose to apply the Hippodamian model (or grid plan), invented in Asia Minor two thousand years earlier. The grid layout brought a number of advantages: it was easy to construct, it was easy for real-estate developers to sell, and it did not stamp a center on cities, allowing them to expand in all directions.
In US cities, the gridiron layout made it easier to find buildings. In New York, for instance, the streets and avenues are numbered in ascending order, providing easy coordinates to locate the different blocks.
Numbering is more complex in cities with less regular layouts. In Paris, for instance, building numbers were only introduced in 1805 after initial tests under the reign of Louis XVI.
Japan relies on neither numbers nor addresses, making finding your destination something of a feat! True to their penchant for technology, many Japanese enter the telephone number of the place they want in their GPS and find it that way!
As these urban areas grew, the use of horse-drawn trams became more common, creating a network that defined city centers. The grid-plan approach quickly became the bread-and-butter design for North American urban planners, regardless of geographical limitations.
Philadelphia, which literally means the "city of brotherly love", was founded by William Penn in 1681. The King of England gave Penn land (which would later become Pennsylvania) to pay off a debt incurred by his father. A Quaker, Penn set off for America to build a community based on freedom of worship. Although he owned the land, he chose to buy it from the native Indians to help foster smoother relations. The city was built in a grid layout between the Delaware River and one of its tributaries. Philadelphia quickly grew to become the second-largest city in the country by 1700.
Seen as the country's intellectual capital (home to booming education and publishing sectors), Philadelphia played a crucial part in the American Revolution and played host to the Second Continental Congress, which led to the signing of the American Declaration of Independence on July 4, 1776. Philadelphia then enjoyed a long period of growth in industry, business and population, boosted by nearby mining operations in the Appalachian Mountains. The city's economic decline, beginning in the 1950s, led to a number of social problems that pushed the middle classes out towards the suburbs.
