Hospital of Innocents (Ospedale degli Innocenti)
The building that invented Renaissance proportion — each bay is a perfect cube, and you can see it with your own eyes.

Brunelleschi's 1419 loggia on Piazza SS. Annunziata is considered the first pure Early Renaissance structure. Commissioned by Florence's Silk Guild as a foundling hospital, it replaced medieval pointed arches with round ones and made proportion literal: column height equals bay width equals arcade depth. Today it houses an art museum and the UNICEF Innocenti Research Centre.
What to look for
- Andrea della Robbia's glazed blue terracotta roundels — babies in relief fill the arch spandrels, marking the building's original purpose as a foundling hospital
- The cube geometry: column height, intercolumniation width, and arcade width are all equal — step back from the loggia and the math becomes visible
- Tabernacle windows with triangular pediments on the upper floor, which was not yet built when Benozzo Gozzoli painted the building in the background of his 1464–65 fresco
The nine-bay loggia faces Piazza SS. Annunziata and is viewable from the square; the art museum is inside the building.
