In architecture, a loggia is a covered exterior gallery or corridor, usually on an upper level, but 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.

A portico is a porch leading to the entrance of a building, or extended as a colonnade, with a roof structure over a walkway, supported by columns or enclosed by walls. This idea was widely used in ancient Greece and has influenced many cultures, including most Western cultures.
