Medieval bridges were essential structures built during the Middle Ages, primarily from the 5th to the late 15th century. They were often made of stone or wood and designed to connect towns, facilitate trade, and improve transportation. Many medieval bridges featured arches, which helped distribute weight and allowed for longer spans over rivers and valleys. Some famous examples of medieval bridges include the Ponte Vecchio in Florence and the Bridge of Alcántara in Spain. These bridges not only served practical purposes but also showcased the architectural skills of the time, often adorned with sculptures and decorative elements that reflected the culture and artistry of the era.
