Defensive Purpose: The primary function of Hadrian's Wall was to keep out invaders from the north, specifically the Picts. The wall acted as a physical barrier, preventing raids and invasions, and helping to maintain peace in the Roman-controlled territories.

Milecastles and Forts: Throughout the length of the wall, there were 80 milecastles, which were small forts spaced about every mile. These milecastles housed soldiers and acted as watchtowers. In addition, there were larger forts, such as Housesteads and Vindolanda, where Roman troops were stationed in greater numbers. These forts provided the necessary infrastructure for sustaining Roman forces on the frontier.

Vicus (Civilian Settlements): In some areas, Roman civilian settlements, known as vicus, grew up around the forts. These settlements housed traders, artisans, and other non-military personnel who supported the army and provided goods and services to the soldiers.

Hadrian's Wall Path: Today, a significant part of the wall can still be visited along the Hadrian’s Wall Path, a popular long-distance trail that allows hikers to experience the rich history and natural beauty of the area. The path offers a scenic route that passes through many of the key sites along the wall, including forts, milecastles, and sections of the wall itself.

Roman Engineering: The wall itself is a marvel of Roman engineering. The Romans built it with meticulous attention to detail, using a combination of stone and turf depending on the local terrain. In some areas, the wall stands over 15 feet tall, while in others, it has been reduced to rubble over the centuries. shutdown123
