High quality, print-quality, plan of Borovicium (Housesteads) at Hadrian's Wall. 'This fort measures about 360 by 600 ft and covers a bit less than 5 acres....Chief among the interior stone buildings are the Headquarters, a rectangular structure with one entrance that opens on a small cloistered court (4), then to a second open court (7) and finally to a row of five rooms (8-12) containing the shrine for official worship, the treasury and other offices. Officers quarters (ix, xi, xii) are nearby as is the storehouse (viii). At the two ends were barracks (i --> vi; xiii --> xviii)' [quoted and paraphrased from The Encyclopedia Brittanica, 11th ed, from which the image is taken]
