How did Saint Peter die?

Saint Peter was crucified in Nero’s circus on Vatican Hill, sometime between 64 and 68 A.D.. He was crucified upside down because he felt unworthy to die the same way as his Lord. Afterwards he was laid to rest in a nearby cemetery. That cemetery can be seen today in excavations under St. Peter’s Basilica, and the remains of a 2nd century shrine built over the burial spot. In the 1960s bones believed to be Peter’s were found preserved in its wall and today the box containing them can be seen in a chapel under the papal altar.
