Things to see
The well is almost 175 ft deep; it is illuminated by 72 large windows.
The exterior is a large and low cylindrical structure ornate with Farnesian lilies; the lilies were chose because the well was completed under Pope Paul III a member of the Farnese family.
There are two doors diametrically opposite, one to enter the well and the other one to leave it.
It is a tradition once you reach the bottom of the St. Patrick’s well to throw a coin into the water so that one day you will be back in Orvieto.
