Topic: Tell me a short, interesting fact about

One fascinating fact about the Roman Empire is that it used a complex system of roads, known as the "Viae Romanae," that spanned an incredible 80,000 kilometers (about 50,000 miles) in total length. These roads facilitated the movement of soldiers, goods, and ideas throughout the vast expanse of the empire, and many are still in use today. Among the most famous is the Appian Way, which stretches from Rome all the way to the port city of Brindisi in the southeast of Italy.
