Giant order

In classical architecture, a giant order, also known as colossal order, is an order whose columns or pilasters span two (or more) storeys. 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.^[1]

The giant order as such was unknown to antiquity, although most ancient buildings using formal orders lacked upper storeys. To an extent buildings with giant orders resemble a Roman temple adapted for post-classical use,^[2] as many were (the survivors have now usually been stripped of later filling-in).
