The Roman Empire faced several challenges in managing the vast territories they controlled, particularly concerning the safety and comfort of travelers. To help travelers find their way, the Romans installed milestones along the roads, which served as guide posts indicating distances to nearby towns and other important information. For safety, they deployed military units to patrol the roads, ensuring that travelers could journey without fear of threats. Additionally, to provide rest and sustenance, the Romans constructed mansiones, which were designated stops offering food and lodging for weary travelers. This comprehensive approach helped facilitate trade and communication across the empire.
