How the Dome Conquered the World

7 stops

From the arch to the vault to the dome itself: one structural idea, traced from Rome's Pantheon through Byzantium and the Renaissance to a Chicago houseboat of stone.

Stop 1 of 7.
Elements and Materials

Start with the simple curve that carries weight in compression instead of bending.

Stop 2 of 7.
Elements and Materials

Stop 3 of 7.
Elements and Materials

Stop 4 of 7.
Buildings and Structures

Rome's Pantheon is the dome's first great monument, its height equal to its own diameter.

Stop 5 of 7.
Buildings and Structures

Byzantium solves the problem of setting a round dome over a square room with the pendentive.

Stop 6 of 7.
Buildings and Structures

The Renaissance brings the dome home to secular life: Palladio's Villa Rotonda quotes the Pantheon directly.

Stop 7 of 7.
Buildings and Structures

And it ends at St. Peter's, where Michelangelo's dome closes the largest church in Christendom.
