The Ospedale degli Innocenti is a historical building in Florence, Italy. Designed by Filippo Brunelleschi, who received the commission in 1419 from the Arte della Lana. It was originally a children's orphanage. It is regarded as a notable example of early Italian Renaissance architecture. The hospital, which features a nine bay loggia facing the Piazza SS. Annunziata, was built and managed by the "Arte della Seta" or SilkGuild of Florence. That guild was one of the wealthiest in the city and, like most guilds, took upon itself philanthropic duties. The façade is made up of nine semicircular arches springing from columns of the Composite order.
