Caravansaries were roadside inns that provided shelter and services to travelers and their animals along trade routes, particularly during the Silk Road era. These establishments were essential for merchants and pilgrims, offering a safe place to rest, food, and water. They typically featured large courtyards for animals and storage, as well as rooms for guests. Often built in strategic locations, caravansaries facilitated trade and cultural exchange between different regions. They were commonly found in areas like Persia, Turkey, and North Africa, reflecting the importance of hospitality in Islamic culture. Many of these structures still stand today, showcasing historical architecture.
