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.

Palazzo Strozzi, 1484

The Strozzi family was another infamous and powerful Florentine family. Giuliano da Sangallo (1443-1516) created a model that was meant to out do the rival Medici family. Their Palazzo, started in 1443, follows along the same lines as the Medici palace by Michelozzo with an emphasis on modesty and civic pride.There are some important changes though. The building is slightly taller, the stonework is more refined and the gradation between the stories is much more subtle. The proportions are more harmonious and the internal symmetry has advanced.
