Concatenation (architecture)

The concatenation (enchainement) is an architectural composition that unites chaining parts together—as with separate elements in long façades, with the fronts being brought forward or recessed.

The concatenation is different from the serliana that usually employs a single order on which both the arches and the architrave rest.

As a compositional element, it saw new interest in the first half of the 15th century, becoming a fundamental syntagm of the classical architecture.

In the Renaissance architecture, the concatenation was widely used in all types of buildings, internal courtyards, and cloisters.

William Kent and other Palladians favoured concatenated façades for their articulation.
