Exterior
The exterior of the Memorial echoes a classic Greek temple and features Yule marble quarried from Colorado. The structure measures 189.7 by 118.5 feet (57.8 by 36.1 m) and is 99 feet (30 m) tall. It is surrounded by a peristyle of 36 fluted Doric columns, one for each of the 36 states in the Union at the time of Lincoln's death, and two columns in-antis at the entrance behind the colonnade. The columns stand 44 feet (13 m) tall with a base diameter of 7.5 feet (2.3 m). Each column is built from 12 drums including the capital. The columns, like the exterior walls and facades, are inclined slightly toward the building's interior. This is to compensate for perspective distortions which would otherwise make the memorial appear to bulge out at the top when compared with the bottom, a common feature of Ancient Greek architecture.
