The memorial, designed by Henry Bacon, after ancient Greek temples, stands 190 feet long, 119 feet wide, and almost 100 feet high. It is surrounded by a peristyle of 36 fluted Doric columns, one for each of the thirty six states in the Union at the time of Lincoln's death, and two columns in-antis at the entrance behind the colonnade.
