A type of decorative architectural frame, usually found around a niche, door, or window. An aedicula is made up of a pediment and entablature supported by columns, pilasters, or piers.
In Roman religion, an aedicula (pl. aediculae) is a small shrine. The word aedicula is the diminutive of the Latin aedis or aedes, a temple or house; thus, an aedicula is literally a small house or temple.
