 With the end of imperial authority in the West, and the fall of big cities, along with the arrival of new populations that governed the Italian peninsula (Eruli, Goti, Longobardi), a sudden migration away from the big cities occurred.It’s exactly during this time that, close to the thermal bath’s, a small group of people will move to the base of Monte San Marco around the year 1000.A Benedictine monastery was already present here which was most likely built on an small Sunni fortress which was then used as a look out post.
