A number of significant Roman Period buildings and artifacts were excavated by the University of Michigan expedition to Karanis. The site was an agricultural center and many large graineries were documented at the site. Husselman (1952:69) and Ellis (1992:19) notes that the largest grainery (C65) excavated at the site is directly across the street from a large building that served as the "military barracks and headquarters of the detachment legionares or auxiliaries stationed at Karanis." Grainery C56 measured 18.5 by 16 meters with a height of 10 meters (3 stories); it consisted of 42 storerooms which were each divided into four parts. The exposed portion of the proposed barracks measures 16 meteres wide and 32.5 meters in length. Coins excavated at the site begin with Ptolemy VI and VII (131 examples) and continue with the greatest number during Probus in AD 276 - 282 (4,469 examples). Coinage ends with Arcadius in AD 395 - 408 (165 examples).
