One example that best represents the use of optical illusions in Greek and Greek-inspired American architecture is the Parthenon in Athens, Greece. The columns of the Parthenon are slightly curved and lean inward, creating an optical illusion that makes the building appear straight and symmetrical when viewed from a distance. This design technique, known as entasis, was used to correct the perceived distortion caused by the building's massive size and to create a sense of harmony and balance in the overall structure. In American architecture, buildings such as the United States Capitol in Washington, D.C. and the Lincoln Memorial also incorporate elements of Greek design, including entasis, to create a sense of grandeur and monumentality.
