Comagena

Comagena was a fortified Roman camp on the Danube, on the site of the modern town of Tulln on the Danube in Lower Austria [1]. Built as a defensive work along the Norican frontier, it originally housed an ala of up to 500 cavalry troops (ala I Commagenorum) [1]. Several phases of rebuilding at the site have been identified: it was established, as an earth-and-timber encampment, in the late 1st century AD, probably under Domitian, and in the early 2nd century stone fortifications were constructed [1]. In its later days the fort served as the base of a naval fleet (the classis Comaginensis), as well as a cavalry regiment (equites promoti) [1]. Excavations to the west and south of the fort have uncovered evidence of at least two associated vici and three graveyards [1].
