The Jefferson Memorial Column Type is an Ionic order of architecture, which is one of the three classical orders of ancient Greek and Roman architecture. It is characterized by its volutes, or spiral scrolls, which are found at the top of the column. The Ionic order was developed in the mid-5th century BC and is often used in the construction of temples and other public buildings. The Jefferson Memorial Column Type is a variation of the Ionic order, which was designed by architect John Russell Pope for the Jefferson Memorial in Washington, D.C.
