Arris is a city located in Algeria. It serves as a geographical location within the country's territory.
While "arris" is also a technical term in architecture, it refers to the sharp edge formed by the intersection of two surfaces. Examples include the corner of a masonry unit, the edge of timber in framing, or the junction between planes of plaster. In classical architecture, the term specifically describes the raised edges that separate the flutings in a Doric column.
