Madonna di San Biagio, Antonio Sangallo the Elder
Built by Sangallo the Elder (1455-1534), a Florentine architect from a family of many architects. This pilgrimage church in Montepulciano was worked on from 1518 to 1529, and then again from 1545 to 1564. Sangallo started with the ideas behind Giuliano Sangallo's Sta. Maria Carceri (Prato) and Bramante's St. Peter's. He went with a centralized Greek cross plan with four towers (only one was built). There are no aisles, a pilastered drum and a central hemispherical dome. Sta. Maria di San Biagio is an example in geometric precision.
