In architecture, a loggia (/ˈloʊdʒ(i)ə/ LOH-j(ee-)ə, usually UK: /ˈlɒdʒ(i)ə/ LOJ-(ee-)ə, Italian: [ˈlɔddʒa]) is a covered exterior gallery or corridor, often on an upper level, sometimes on the ground level of a building. The corridor is open to the elements because its outer wall is only partial, with the upper part usually supported by a series of columns or arches.[1] An overhanging loggia may be supported by a baldresca.[2]
From the early Middle Ages, nearly every Italian comune had an open arched loggia in its main square, which served as a "symbol of communal justice and government and as a stage for civic ceremony".[3]
In Italian architecture, a loggia is also a small garden structure or house built on the roof of a residence, open on one or more sides, to enjoy cooling winds and the view.[4] They were especially popular in the 17th century and are prominent in Rome and Bologna, Italy.
