Cortile del Belvedere

The Cortile del Belvedere, the Belvedere Courtyard, designed by Donato Bramante from 1506 onward, was a major architectural work of the High Renaissance at the Vatican Palace in Rome; its concept and details reverberated in courtyard design, formalized piazzas and garden plans throughout Western Europe for centuries. Conceived as a single enclosed space, the long Belvedere court connected the Vatican Palace with the Villa Belvedere in a series of terraces connected by stairs, and was contained on its sides by narrow wings.

Bramante did not see the work completed, and before the end of the sixteenth century it had been irretrievably altered by a building across the court, dividing it into two separate courtyards.

Innocent VIII began construction of the Villa Belvedere on the high ground overlooking old St Peter's Basilica, in 1484. Here, where the breezes could tame the Roman summer, he had the Florentine architect Antonio Pollaiuolo, design and complete by 1487 a little summerhouse, which also offered spectacular views to the east of central Rome and north to the pastures beyond the Castel Sant'Angelo (the Prati di Castello). This villa suburbana was the first pleasure house to be built in Rome since Antiquity.

When Pope Julius II came to the throne in 1503, he moved his growing collection of Roman sculpture here, to an enclosed courtyard within the Villa Belvedere itself. Soon after its discovery, Julius purchased the ancient sculpture of Laocoön and His Sons and brought it here by 1506. A short time later, the statue of Apollo became part of the collection, henceforth to be known as the Apollo Belvedere, as did the heroic male torso known as the Belvedere Torso.

Julius commissioned Bramante to link the Vatican Palace with the Villa Belvedere. Bramante's design is commemorated in a fresco at the Castel Sant'Angelo; he regularized the slope as a set of terraces, linked by rigorously symmetrical stairs on the central longitudinal axis, to create a sequence of formal spaces that was unparalleled in Europe, both in its scale and in its architectural unity.
