Today In History – September 11

On September 11, 1941, construction of the Pentagon began in Arlington, Virginia. The Pentagon is the headquarters of the United States Department of Defense and serves as the symbol of the country’s military might. The construction project was initiated by President Franklin D. Roosevelt, who wanted to consolidate the scattered offices of the War Department, Navy Department, and the newly formed Department of the Air Force into one building.

The construction of the Pentagon was a massive undertaking, requiring the efforts of thousands of workers. The project was completed in just over a year, with the building being dedicated on January 15, 1943. The Pentagon covers an area of 29 acres and has five sides, each of which is 921 feet long. The building has over 17 miles of corridors and contains 17.5 million cubic feet of space.

The construction of the Pentagon was not without its challenges. The site chosen for the building was originally a marshland, which had to be drained before construction could begin. The construction site was also located near the flight path of Washington National Airport, which meant that the building had to be designed to withstand the vibrations caused by passing airplanes.

One of the most significant challenges faced during the Pentagon construction was the material shortage caused by the onset of World War II. The building was designed to use steel and concrete, which were in short supply due to the war effort. To overcome this, the architects of the building came up with a unique design that used less steel and concrete than a traditional building of its size.

The attack on Pearl Harbor on December 7, 1941, affected the Pentagon’s construction. The attack forced the United States to enter World War II, and the country’s resources were redirected towards the war effort. Despite this setback, construction of the Pentagon continued, and the building was completed on time.

Today, the Pentagon remains an iconic symbol of the United States military and serves as the headquarters of the Department of Defense. The building has undergone several renovations and upgrades over the years, including the addition of a new wing in 2011. The Pentagon continues to be an essential part of the country’s history and a testament to the resilience and determination of its people.
