what metal is on top of the washington monument
Washington Monument The Washington Monument is a hollow Egyptian style stone obelisk with a 500-foot (152.4 m) tall column and a 55-foot (16.8 m) tall pyramidion. Its walls are 15 feet (4.6 m) thick at its base and 1 1⁄2 feet (0.46 m) thick at their top. The marble pyramidion has thin walls only 7 inches (18 cm) thick supported by six arches, two between opposite walls that cross at the center of the pyramidion and four smaller corner arches. The top of the pyramidion is a large marble capstone with a small aluminum pyramid at its apex with inscriptions on all four sides. The lowest 150 feet (45.7 m) of the walls, constructed during the first phase 1848–54, are composed of a pile of bluestone gneiss rubble stones (not finished stones) held together by a large amount of mortar with a facade of semi-finished marble stones about 1 1⁄4 feet (0.4 m) thick. The upper 350 feet (106.7 m) of the walls, constructed during the second phase 1880–84, are composed of finished marble surface stones, half of which project into the walls, partially backed by finished granite stones.[15]

United States Capitol On the ground floor is an area known as the Crypt. It was intended to be the burial place of George Washington, with a ringed balustrade at the center of the Rotunda above looking down to his tomb. However, under the stipulations of his last will, Washington was buried at Mount Vernon. The Crypt houses exhibits on the history of the Capitol. A compass star inlaid in the floor marks the point at which Washington, D.C. is divided into its four quadrants and is the basis for how addresses in Washington, D.C., are designated (NE, NW, SE, or SW). However, due to the retrocession of the Virginia portions of the District, the geographic center of the city lies near the White House.
