پل (Pol) is the Persian word for "bridge." It refers to a structure built to span physical obstacles, such as rivers or roads, allowing people and vehicles to cross. Bridges can be made from various materials, including wood, steel, and concrete, and come in different designs, such as arch, beam, and suspension. In Iran, bridges have significant historical and cultural importance. Many famous bridges, like the Si-o-se-pol in Isfahan, showcase intricate architecture and serve as popular tourist attractions. These structures not only facilitate transportation but also symbolize connection and unity within communities.
