Isola Comacina is a small wooded island of Italy’s Lake Como, administratively a part of the commune of Ossuccio. It is located close to the western shore of the Como arm of the lake in front of a gulf known as Zoca de l'oli, a Lombard name referring to the local small-scale production of olive oil. In the late 6th century (c. 587) the island was a remaining Roman stronghold under Francio, a subordinate of Narses; though the areas surrounding Lake Como were entirely controlled by the Lombards. The island was besieged for a good deal of time by the Lombards under Authari who released Francio to flee back to Narses' capital at Ravenna.
