Ospedale degli Innocenti
Built (1419-1424) and conceived by Brunelleschi, this was the first example of Renaissance architecture with its roots in classical antiquity. There is a long horizontal entablature, pedimented (low pitched ornamental, triangular pieces from Grecian architecture) windows, Corinthian columns, and a system of harmonious symmetry. The design is based on simple shapes, squares and round arches, which are laid out mathematically, i.e. the height of one column equals the distance between the next column and the distance between the column and the wall. We also see the introduction of pietra serena, which is a grey sandstone used to contrast the stucco.
