According to research carried out by some paleontologists, it was discovered that the stone used for the erection of St. Ambrose walls holds the residues of an unbelievable resident- a dinosaur that has been fossilized inside the walls. The combination of the nasal cavity, teeth, and cranium that was found within the walls appeared to be the skull of a dinosaur. It is believed that this stone, known as Broccatello (mined in Arzo, Switzerland) may have been the home to this fossil for long, about 190 million years ago.
