Very nice, well done, and interesting spot to visit. Won't take more than 20-30 minutes to walk through the caves, but inside you will find extremely interesting information about the discovery of the caves themselves and thoughts on what different parts of the caves were used for. They also have interesting pieces found in the cave, along with a lovely courtyard to sit in and enjoy while having a glass of wine or a pastry. What's incredibly interesting to keep in mind is that the city we know now as Orvieto, and indeed, probably many cities that we now know and love across Italy, have been built on top of cave systems such as this. It's fascinating to think what lies underneath when walking around Umbria, and especially the Orvieto area. I think this is a very interesting spot and found it very worth my time.
