History and description

Michelangelo started the work in 1546, during the papacy of Paolo III Farnese. When Michelangelo died (1564), work was halted until Giacomo della Porta, together with Domenico Fontana, started again in 1588. They used 800 workers.

Initially the idea was to decorate the inside with mosaics. This plan was cancelled when the architects realized that this way it would be impossible to finish construction before the 1600 Jubilee.

There are metal rings around the inner layer. These were added in the 18th century after cracks had appeared in the cupola’s surface. The bronze globe topping the cupola has a diameter of 3,3 meters.

The egg-shaped dome is also supported by four 18-meter-long crossbeams.
