Comagena

Comagena was a Roman fort (castrum) located in the Roman province of Noricum, on the Danube Limes. Today, it corresponds to the modern-day town of Tulln an der Donau, Austria.

The fort was an important strategic point, controlling river traffic and guarding the frontier against incursions from Germanic tribes. It was established in the 1st century AD, likely during the reign of Emperor Claudius, and remained occupied until the end of Roman rule in Noricum in the 5th century AD.

Archaeological excavations have revealed evidence of several phases of construction and rebuilding at Comagena, reflecting the changing security situation and evolving military needs. The fort's layout typically consisted of a rectangular enclosure with towers and gates, housing barracks, administrative buildings, granaries, and other structures necessary for a Roman military garrison.

Alongside the military structures, a civilian settlement (vicus) developed around the fort, providing services and goods to the soldiers and their families. This vicus likely included workshops, taverns, shops, and housing.

The name "Comagena" is of Celtic origin, suggesting a pre-Roman settlement in the area. Its strategic location on the Danube continued to make Tulln an important site throughout subsequent historical periods. While the Roman fort of Comagena no longer stands, its remains offer valuable insights into the Roman military presence and administration in Noricum.
