The Pentagon

The Pentagon contains 6.5 million square feet of space across five floors, connected by 17.5 miles of corridors made of concrete and limestone.

Construction of the Pentagon began on September 11, 1941, as the United States prepared for involvement in World War II under architect George Bergstrom.

The Pentagon Memorial includes 184 illuminated benches arranged by age, from 3 to 71, representing each person who died in the 2001 attack.

The Pentagon hosts guided tours for visitors who must make reservations at least 14 days in advance through their congressional representatives.

The building features a central courtyard known as Ground Zero Cafe, named during the Cold War when Soviet missiles targeted the location.
