Proportion is a central principle of architectural theory and an important connection between mathematics and art. It is the visual effect of the relationship of the various objects and spaces that make up a structure to one another and to the whole. These relationships are often governed by multiples of a standard unit of length known as a "module".
Proportion in architecture was discussed by Vitruvius, Leon Battista Alberti, Andrea Palladio, and Le Corbusier among others.

The Tempietto del Bramante is a martyrium designed by Donato Bramante to commemorate the site traditionally regarded as the location of Saint Peter’s crucifixion. The small, freestanding chapel was commissioned by Ferdinand II of Aragon and Isabella I of Castile and was completed c. 1502 for the cloister of San Pietro in Montorio in Rome, Italy. The structure is considered a masterpiece of High Renaissance architecture, with scholars and architects noting Bramante’s harmonious proportions and his symbolic adaptation of Classical and early Christian architectural elements.
