Europe’s major cities during medieval times would most likely be located near what is known as "natural harbors" or bodies of water like rivers, lakes, or seas. These locations allowed for efficient transportation and trade, as waterways provided a means of moving goods and people. Additionally, being near water bodies allowed for access to fishing, which was an important source of sustenance during that time. Being near water bodies also provided opportunities for defense as they could serve as natural barriers against invaders. Consequently, major medieval cities such as London, Paris, Venice, and Barcelona were often situated near coasts, rivers, or strategic inland waterways.
