In Classical architecture, a giant order is an order whose columns or pilasters span two (or more) stories. At the same time, smaller orders may feature in arcades or window and door framings within the storeys that are embraced by the giant order.

One of the earliest uses of this feature was at the Basilica di Sant'Andrea di Mantova (pictured above), designed by Leon Battista Alberti and begun in 1472.
