A show of might is built of bleached yellow stone atop a steep hillside very high above the city. Some view enthusiasts claim that a sharp-eyed observer can see all the way to the Mediterranean on a clear day, but that’s probably an oxygen-deprivation vision induced by the hearty climb through narrow medieval lanes and up the pine-scented hillside. Hyberbole aside, views across the Umbrian plain below are wonderful and quite a bit more exhilarating than the dull displays of costumes and weapons in the restored keep and soldiers quarters; save the admission fee for a glass of wine when you get back down.
