Modern Cities Influenced by Ancient Hippodamian Urban Planning

The Hippodamian Plan, also known as the grid plan or gridiron plan, is one of the earliest known urban planning systems. It is named after Hippodamus of Miletus, a 5th-century BCE Greek architect and urban planner, often referred to as the "father of European urban planning." Hippodamus introduced this system in the city of Miletus, following its destruction by the Persians in 494 BCE. His approach was revolutionary for its time, emphasizing the importance of order, rationality, and symmetry in urban design. The Hippodamian Plan consists of a layout of streets intersecting at right angles, forming a grid of uniform rectangular or square plots. This methodology not only facilitated navigation and land division but also enhanced civic administration and urban development.

Today, many modern cities around the world have incorporated the principles of the Hippodamian Plan, adapting it to their unique contexts and needs. Here are some notable examples:

1. New York City, USA
