The Tempietto by Donato Bramante in the cloister of San Pietro in Montorio, literally "St. Peter at the Golden Hill", is seen as the perfect example of High Renaissance. The little round church was built by the Spanish Franciscans of the royal couple, Ferdinand and Isabella of Spain, who wanted to mark the building to the place where St. Peter would be crucified.
In the time of Bramante, the circular shape and architectural re-upgraded, but the Tempietto (literally, "temple") was the first full dome church since Roman times. This makes the building a prime example of the so-called central plan, a way of building to a central point around which Christianity, previously only baptism, burial and Marian chapels was applied, other religious buildings were traditionally in the style of axial building design.
The three steps high base, the cella - a sacred area where only the priest may be - surrounded by a colonnade in the Vestal style of the temples in Tivoli and the Tiber in Rome. Around the cell is surrounded by a balcony and crowned with a dome. From the ground to the top of the dome, the temple is about 13 meters high.
Like the early Christian martyria which the building is inspired Tempietto has no practical function, but serves as a monument commemorating - in this case the crucifixion of Peter. Naturally, the veneration of Peter is central to the decoration of the church. The above-ground rooms contain many statues of the apostle and his attributes. For example, in a frieze above the Doric columns the keys of Peter and carved into the underground chapel (now closed) has a hole in the ground symbolizing the place where the cross would be founded.
