The Gothic-style Orsanmichele Church and Museum is a champion which is best known for its Renaissance architecture. With luxurious entryways and windows, probably the most established stained glass in Florence, and sculptures by Brunelleschi, Ghiberti, Della Robbia, Nanni di Banco, and Donatello, this generally secret milestone merits a visit. The engineering of the loggia was described by enormous angled openings for the market region where wheat, straw and grain were commerced. The subsequent floor was given to workplaces, while the third floor housed one of the city's civil grain storage facilities, kept up to withstand starvation or attack.
