Germanicum

Germanicum (also Castra Germanicum) was a Roman cavalry fort (ala fort) of the Raetian Limes at modern Kösching in Bavaria, north of the Danube near Ingolstadt, occupied from the spring of AD 80 to about 242/243.⁸ Its ancient name is known from a building inscription, and it appears as a station, Germanico, on the Tabula Peutingeriana, the Roman road map.¹^•² The name is said to recall that Kösching held the first fort north of the Danube, on the Germanic side of the river.³

Location and identification

The fort lay on a high terrace of the Riss glaciation on the northern bank of the Danube, in the market town of Kösching about 8 km northeast of Ingolstadt.⁴ In the Roman road network it stood on the great military road from the Danube crossing at Eining toward Weißenburg, between the forts of Pförring (Celeusum) and Pfünz (Vetoniana).⁴ The Tabula Peutingeriana lists the station as Germanico, 9 Roman miles from one neighbor and 12 from the other, and the Realencyclopädie entry identifies it with Kösching.²^•⁴

The wood-earth fort of AD 80

Foundation under Titus. A two-sided building inscription found in 1906 during construction of the girls' school dates the original wood-earth camp to the reign of Titus, spring AD 80; the inscription names the emperor and the governor Caius Saturius, though the unit's name was not preserved.⁹ The oldest known dendrochronological date from the site, a beam from the "Bachaue" dated to 79, fits the inscription.³ The original stone of the inscription was destroyed in Munich during the Second World War, but a cast survives.³

The wood fort's ditch differed in position from the later stone defenses: the younger fortification overlapped the older camp in its northern half.

An even earlier military presence may lie nearby: in 2002, massive wooden posts about 300 m east of the ala fort were dated to 81/82 and belong to an older troop camp whose exact location and size are not yet known.⁵

The stone fort and its garrisons

The stone fort was built in the reign of Antoninus Pius (138–161), with a building inscription of 141 attesting the Ala I Flavia Gemelliana; the fort covered about 4.3 ha, with newer investigations indicating a nearly square plan of about 197 x 197 m, and its praetorial front faced south toward the Danube.¹ The Realencyclopädie gives the fort area as 42,900 square meters and states that it housed an ala of 500 men.⁴

The garrison sequence rests on diplomas and inscriptions. The Ala I Augusta Thracum, attested in Raetia by a military diploma of 107, may have been responsible for building the wood fort and formed the first garrison.

Vicus, roads, and milestones

Roads connected Germanicum with the forts Pfünz and Pförring, and the Roman road from Pförring via Theißing to Kösching and on over Böhmfeld to Pfünz is still visible as a track over much of its length, with cemeteries on both sides of its western line.¹

End of the occupation

A hoard of 240 denarii found about 125 m east of the fort wall closes with a coin minted in the summer of 241 under Gordian III (238–244). The local history records the fort as abandoned around 245, with Germanic settlements on the Eixelberg.⁶

The site today

The fort area is completely built over, and its outline survives only vaguely in the town plan. The parish church of Mariä Himmelfahrt stands over the principia, the headquarters building at the center of the fort, and a "Römergarten" south of the church, laid out in 2010, displays full-size reconstructions of Roman inscription stones.¹^•⁷ The Museum Markt Kösching devotes most of its archaeology section to the fort, including weapons, glass, terra sigillata, amphoras, and a Roman milestone found in 1984.³
