Hippodamus was an ancient Greek architect and urban planner, often referred to as the "father of urban planning." He is best known for his innovative ideas about city design, particularly his grid layout, which organized streets in a systematic way. This approach made cities easier to navigate and more efficient, influencing urban planning for centuries. His most famous project was the design of the city of Miletus, which featured wide streets and public spaces. Hippodamus believed that a well-planned city could improve the quality of life for its inhabitants. His ideas laid the groundwork for modern city planning and continue to inspire architects today.
