Assisi se extende en las laderas del monte Subasio, encima de la llanura donde corren los ríos Topino y Chiascio. No obstante su origen de época romana, el aspecto actual de Assisi, tanto en los edificios como en la urbanización, seguramente fue determinado por el desarrollo medioeval.
Bastia Umbra, which is situated in the plain dominated by Mount Subasio, is now an important economic center in the Assisi area.
The town of Bettona can boast ancient Etruscan origins, insofar as its foundation is dated at around the 8th and 7th centuries B.C.
The first records of an inhabited settlement in Cannara area go back to around the Ist century B.C. This is probably the date of the town's foundation, but one believes that the settlement which the Romans called "Castrum Canarii", became a real town only after the barbaric invasions in Italy.
