Legio undecima Claudia ("Claudius' Eleventh Legion") was a legion of the Imperial Roman army. XI Claudia dates back to the two legions (the other was the XIIth) recruited by Julius Caesar to invade Gallia in 58 BC, and it existed at least until the early 5th century, guarding lower Danube in Durostorum (modern Silistra, Bulgaria). The emblem of the legion is not known; it could have been, as all of the Caesar's legions, the bull or possibly the she-wolf lactating the twins.
The XI and XII legions were levied by Caesar for his Helvetii campaign in 58 BC. The legion fought in the Battle against the Nervians, and probably fought at the Siege of Alesia too. During the civil war, the Eleventh legion fought for Caesar at the Battle of Dyrrhachium and at Pharsalus. The legion was disbanded in 45 BC, and its veterans were offered lands at Bojano, which received the name of Bovianum Undecumanorum, "Bovianum of the members of the eleventh".
Legio was a Roman military camp south of Tel Megiddo in the Roman province of Galilee.
The approximate location of the camp of the Legio VI Ferrata was known from the persistence of its name in the form Lajjun by which a Palestinian Arab village was known.
It was close to the ancient town of Rimmon, perhaps the Hadad-rimmon of Zechariah 12:11, which in the 3rd century was renamed Maximianopolis (City of Maximian) by Diocletian in honour of his co-emperor Maximian. Both places were within a single episcopal see, generally called Maximianopolis, but in one list of such sees the name Legionum (genitive plural of the Latin word Legio) is used, where the Greek original has "Maximianopolis".
In 2002–2003, an archaeological survey was made in the Legio region by Yotam Tepper as part of his master's thesis. The survey located the legionary camp on the northern slope of El-Manach hill, the village of Ceparcotani on the adjacent hill, and the city of Maximianopolis on the site of the contemporary Kibbutz Megiddo. In 2013 Tepper and the Jezreel Valley Regional Project dug test trenches measuring approximately 295 feet by 16.5 feet that revealed clear evidence of the camp. No military headquarters of this type for this particular period had yet been excavated in the entire Eastern Empire, and the 2013 excavations uncovered defensive earthworks, a circumvallation rampart, barracks areas and artifacts including roof tiles stamped with the name of the Sixth Legion, coins and fragments of scale armor.
