San Pietro in Montorio
Small Roman circular temples with colonnades have often been used as models, either for single buildings, large or small, or elements such as domes raised on drums, in buildings on another plan such as St Peters, Rome, St Paul's Cathedral in London and the United States Capitol. The great progenitor of these is the Tempietto of Donato Bramante in the courtyard of San Pietro in Montorio in Rome, c. 1502, which has been widely admired ever since.
