Built as a walled fortress by the Romans and watered by their great aqueduct, Segovia began to grow in Visigothic times and came into its own as a rich and powerful city in the Middle Ages. This program documents its history—which in many ways mirrors the history of Spain—through its homes and churches, its highways and byways, the rooms where Alfonso el Sabio wrote his astronomical treatise and where ordinary fullers plied their trade. Segovia is the most Romanesque city in Spain, and the most continuous monument of Spanish history from the beginning of the historical past to today. (35 minutes)
