In the interurban area of the hill several barracks were built for the troops stationed in the capital: in the site of the Basilica of Saint Stephen in the Round there were the Castra Peregrina (built under Trajan and restored several times in the following centuries), close to a large house of the Valerii (domus Valerii). ./cache/en-wikipedia-org-2484.html ./txt/en-wikipedia-org-2484.txt
