The Birth of the Pentagon
On January 15, 1943, the Pentagon, an architectural and military marvel, officially opened its doors in Arlington, Virginia. Designed to serve as the headquarters of the United States Department of Defense, the Pentagon remains the world’s largest office building, both in floor space and historical significance.
Why the Pentagon Was Built
In the early 1940s, as the U.S. prepared for the challenges of World War II, there was an urgent need for a centralized facility to coordinate military operations. Before the Pentagon, the War Department was scattered across numerous buildings, leading to inefficiencies in communication and strategy.
President Franklin D. Roosevelt approved the project in 1941, and construction began on September 11, 1941, just months before the U.S. entered World War II.
Architectural Feat and Unique Design
The Pentagon’s distinctive five-sided design is a result of practicality and ingenuity. Originally planned for a different site with pentagonal boundaries, the design was retained even when the location shifted.
Key features of the Pentagon include:
- 17.5 miles of corridors connecting its five concentric rings.
- A central courtyard spanning five acres, providing an open space for relaxation.
- Its innovative layout ensures that no two points are more than seven minutes apart by walking.
At the time, the project was an engineering triumph, completed in just 16 months—a remarkable feat given its massive scale and wartime challenges.
Role in Military History
From its inception, the Pentagon has been the nerve center of U.S. military operations. During World War II, it played a crucial role in coordinating the efforts of the Army and Navy. Over the decades, it has witnessed pivotal moments in American history, from the Cold War to the Global War on Terrorism.
One of the Pentagon’s most somber days came on September 11, 2001, when it became a target of the terrorist attacks. The tragedy highlighted its enduring symbolism as the heart of U.S. defense and resilience.
