In architecture, a loggia (/ˈl(i)ə/, usually UK: /ˈlɒ(i)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. An overhanging loggia may be supported by a baldresca.

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".

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. They were especially popular in the 17th century and are prominent in Rome and Bologna, Italy.

01Definition of the Roman loggia

The main difference between a loggia and a portico is the role within the functional layout of the building. The portico allows entrance to the inside from the exterior and can be found on vernacular and small scale buildings. Thus, it is found mainly on noble residences and public buildings. A classic use of both is that represented in the mosaics of Basilica of Sant'Apollinare Nuovo of the Royal Palace.

Loggias differ from verandas in that a loggia is a covered exterior gallery that is part of a building, typically open on one or more sides and supported by columns or arches, often overlooking a courtyard or garden. An arcade, by contrast, is a series of arches supported by columns or piers, forming a covered walkway or decorative façade element. While both use arches and columns, a loggia serves as a semi-outdoor room for leisure, whereas an arcade provides shelter and rhythm along a passage or street.

Loggias differ from arcades in that they are more architectural and, in form, are part of the main edifice in which they are located, while verandas are roofed structures attached on the outside of the main building. A "double loggia" occurs when a loggia is located on an upper floor level above a loggia on the floor beneath.
