From a bulging V-shaped ridge almost 1000m above sea level, ENNA lords it over the surrounding hills of central Sicily. The approach to this doughty mountain stronghold is formidable, the road climbing slowly out of the valley and looping across the solid crag to the summit and town. For obvious strategic reasons, Enna was a magnet for successive hostile armies, who in turn besieged and fortified the town, each doing their damnedest to disprove Livy’s description of Enna as inexpugnabilis.
