St. Peter's Basilica in Rome is one of the largest churches in the world. The basilica was constructed between 1506-1626 over the site of the original 4th century St. Peter's Basilica. It was designed by architects including Bramante, Michelangelo, Maderno, and Bernini. The massive dome, one of the largest in the world, rises 120 meters and can be climbed by a small spiral staircase. The interior features a long nave, lavish marble decorations, and many artistic tombs. St. Peter's Square outside features tall colonnades, an obelisk, and fountains designed by Bernini.

bring to the top of the dome.
 The great double dome is made of brick and is 41.5 metres
in interior diameter (almost as large as the Pantheon),

it has a vertical thrust, which is made more emphatic by
the bold ribbing that springs from the paired Corinthian
columns, which appear to be part of the drum
