Isca Legionis

Isca Legionum

Isca Legionis, also known simply as Isca, was a Roman legionary fortress and settlement located in what is now modern-day Caerleon, Wales. It was one of the most important military and administrative centers in Roman Britain during the Roman occupation of the island.

The modern town of Careleon has developed around the site of Isca Legionis, and is often referred to as the “Fortress of the Legions” due to its historical significance. The name by which Caerleon was known in early times has led to its identification with the City of the Legion.


Isca Legionis | 0 to 700 AD

Isca Legionis was founded around 75 AD during the rule of Emperor Vespasian as a fortress for the Second Augustan Legion, also known as Legio II Augusta. The primary purpose of Isca was to serve as a base for the Roman military in the region and to help maintain control over the native Celtic tribes in Wales and the southwest of Britain.

Isca was strategically situated on the River Usk, providing easy access to the coast and serving as a transportation hub. Its location allowed the Roman legions stationed there to control and supervise the region effectively.

The Roman fortress at Isca was a typical example of a legionary base, featuring defensive walls, barracks, granaries, a headquarters building (principia), and other infrastructure necessary for the legion’s operations. The fortress was designed to house a substantial number of Roman soldiers and support personnel.

One of the most remarkable features of Isca Legionis is its well-preserved Roman amphitheater, which could hold around 6,000 spectators. The amphitheater was used for various forms of entertainment, including gladiator contests and other public spectacles.

The Roman presence in Britain began to decline in the fourth and fifth centuries, partly due to pressure from invading barbarian tribes. Isca Legionis was eventually abandoned by the Romans, and the fortress fell into disuse and disrepair during the early medieval period.
