Santo Stefano di Sessanio is a fortified medieval burgh rising on a pre-existent Italic-Roman site. It located at an altitude of 1250 metres deep in the heart of the Apennine mountains near L'Aquila inside the Gran Sasso & Monti della Laga National Park, in Abruzzo. The burgh's current urban structure was established in the Middle Ages during the then nascent castle-building phenomenon and features a landscape dotted by fortified highland habitats, still very much one of the historical and topographical elements characterising Central Italy today.
