Inside Michelangelo's main dome of St. Peter's Basilica
.

Michelangelo's dome of St. Peter's rises to a total height of 448 feet (136.57 meters) and is the tallest dome in the world. Its internal diameter is 136 feet (41.47 meters), slightly smaller than the Pantheon of Ancient Rome and Florence Cathedral of the early Renaissance.  Rising above the alter, it
is supported by four 120 meter high piers. Around the base of the dome are the words from Matthew's Gospel:
.
 "Tu es Petrus et super hanc petram aedificabo ecclesiam mean et tibi dabo claves regni caelorum"
("You are 'Rock' and on this rock I will build my Church, to you I will give the keys of the kingdom of heaven." Mt 16:18)
.
The gigantic black text is lit by the light from 16 large windows, typical of Michelangelo's style, which punctuate the drum. Above the windows, the dome is divided into sixteen ribs and as many segments, decorated by majestic figures on six ascending concentric levels.
