Lincoln Memorial made from material Tennessee marble
Above the colonnade, inscribed on the frieze, are the names of the 36 states in the Union at the time of Lincoln's death and the dates in which they entered the Union. Their names are separated by double wreath medallions in bas-relief. The cornice is composed of a carved scroll regularly interspersed with projecting lions' heads and ornamented with palmetto cresting along the upper edge. Above this on the attic frieze are inscribed the names of the 48 states present at the time of the Memorial's dedication. A bit higher is a garland joined by ribbons and palm leaves, supported by the wings of eagles. All ornamentation on the friezes and cornices was done by Ernest C. Bairstow.The Memorial is anchored in a concrete foundation, 44 to 66 feet (13 to 20 m) in depth, constructed by M. F. Comer and Company and the National Foundation and Engineering Company, and is encompassed by a 187-by-257-foot (57 by 78 m) rectangular granite retaining wall measuring 14 feet (4.3 m) in height.Leading up to the shrine on the east side are the main steps. Beginning at the edge of the Reflecting Pool, the steps rise to the Lincoln Memorial Circle roadway surrounding the edifice, then to the main portal, intermittently spaced with a series of platforms. Flanking the steps as they approach the entrance are two buttresses each crowned with an 11-foot (3.4 m) tall tripod carved from pink Tennessee marble by the Piccirilli Brothers. There are a total of 87 steps (58 steps from the chamber to the plaza and 29 steps from the plaza to the Reflecting Pool).
