Aedicula – (Latin: small house, temple (almshouse)) Small structure intended to house a sacred image or statue. It may also be a niche set into the external wall of a building. The aedicula consists of pillars, columns or pilasters and a gable and was used in Roman temples as an attachment to house a statue.
In the Middle Ages the term aedicula used to denote a small (grave) chapel.
The aedicula has only a decorative function, primarily since the Renaissance it has used as tombs and altars.
