what's at the center of the pentagon
The Pentagon The Pentagon is the world's largest office building, with about 6,500,000 sq ft (600,000 m2), of which 3,700,000 sq ft (340,000 m2) are used as offices.[6][7] Approximately 23,000 military and civilian employees[7] and about 3,000 non-defense support personnel work in the Pentagon. It has five sides, five floors above ground, two basement levels, and five ring corridors per floor with a total of 17.5 mi (28.2 km)[7] of corridors. The Pentagon includes a five-acre (20,000 m2) central plaza, which is shaped like a pentagon and informally known as "ground zero," a nickname originating during the Cold War on the presumption that it would be targeted by the Soviet Union at the outbreak of nuclear war.[8]
Soldiers' and Sailors' Monument (Indianapolis) The Indiana State Soldiers and Sailors Monument is a 284 ft 6 in (86.72 m) neoclassical monument built on Monument Circle, a circular, brick-paved street that intersects Meridian and Market streets in the center of downtown Indianapolis, Indiana. In the years since its public dedication on May 15, 1902, the monument has become an iconic symbol of Indianapolis, the state capital of Indiana. It was added to the National Register of Historic Places on February 13, 1973 and was included in an expansion of the Indiana World War Memorial Plaza National Historic Landmark District in December 2016.[2] It is located in the Washington Street-Monument Circle Historic District. It is also the largest outdoor memorial and the largest of its kind in Indiana.
