You met site and situation as two ways to describe any place. They also explain why cities grow where they do, and why some keep growing while others fade.
Key idea
A city's site is the land it stands on: a harbor, a river crossing, an island, a hill that is easy to defend, a spring. Its situation is its location relative to other places: on a trade route, at a crossroads, near resources and markets.
| City | Site | Situation |
|---|---|---|
| Paris | An island in the Seine (the Île de la Cité), easy to defend and to cross | Center of a rich farming region and of France's roads and railroads |
| New York | A deep, sheltered harbor | The Erie Canal (1825) linked it to the Great Lakes and the Midwest |
| Singapore | A small island with a good harbor | On the Strait of Malacca, one of the world's busiest shipping routes |
| Chicago | Flat, marshy land by Lake Michigan | Where water routes and, later, railroads met, linking East and West |
| Istanbul | Hills by a natural harbor (the Golden Horn) | Where Europe meets Asia and the Black Sea meets the Mediterranean |
Why it works
A good site gets a settlement started: people needed water, defense and a place to land boats. But a site does not change while the world around it does. When trade routes, canals, railroads or airports shift, a city's situation can improve or decline. That is why situation often matters more over time, and why cities spread far beyond their first site.
Worked example: Site or situation?
Which describes Singapore's situation: (a) it is on a small island with a sheltered harbor; (b) it lies on the main shipping route between the Indian and Pacific oceans?
- Site is the land itself: the island and the harbor.
- Situation is the location relative to other places: the shipping route.
Answer: (b) is its situation.
Worked example: A canal changes everything
In 1825 the Erie Canal connected the Hudson River with the Great Lakes. Did it change New York City's site or its situation?
- The land under the city did not change.
- Its connection to the interior did: farm goods from the Midwest could now ship out through its harbor.
Answer: Its situation, which helped it grow into the largest U.S. city.
Common mistake
Thinking a city stays important because of its first site. Many cities grew past their first reason for being; situation often matters more over time. A defensive hill means little today, but a port on a busy route or a hub airport means a lot.
