I know several of them are on a hill, above the roads connecting the different towns.
I distinctly recall having to park and take a funicular up,
It was not Orvieto. It was deep in Umbria, either east or south of Perugia and Assisi. Maybe Spoleto or Spello.
I visited as a day trip years and years ago, probably from Pienza, so it was a long drive to Perugia, Assisi and then this town, which I kind of rushed through.
