In architecture, a loggia ( , usually , ) 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.
