Geography
Modern city planning has seen many different schemes for how a city should look. The most commonly seen pattern is the grid, used for thousands of years in China, independently invented by Alexander the Great's city-planner Dinocrates of Rhodes and favoured by the Romans, while almost a rule in parts of pre-Columbian America. Derry begun in 1613, was the first planned city in Ireland, with the walls being completed five years later. The central diamond within a walled city with four gates was thought to be a good design for defence. The grid pattern was widely copied in the colonies of British North America.
The Ancient Greeks often gave their colonies around the Mediterranean a grid plan. One of the best examples is the city of Priene. This city had different specialized districts, much as is seen in modern city planning today. Fifteen centuries earlier, the Indus Valley Civilization was using grids in such cities as Mohenjo-Daro. In medieval times there was evidence of a preference for linear planning. Good examples are the cities established by various rulers in the south of France and city expansions in old Dutch and Flemish cities.
