The statue of Lincoln, originally designed to be 10 feet (3.0 m) tall, was enlarged to 19 feet (5.8 m) to prevent it from being overwhelmed by the huge chamber. As late as 1920, the decision was made to substitute an open portal for the bronze and glass grille which was to have guarded the entrance.
Construction on the Lincoln Memorial began on February 12, 1914. The building stands at the far western end of the National Mall. The 19th foot tall statue of Lincoln gazes out from a solemn chamber in a building surrounded by 36 columns, each representing a state in the union at the time of the Lincoln's death.
