Hey guys. Back with another crowning jewel of American History. The Pentagon. The headquarters of the US Department of Defense. Built in Washington DC. The Pentagon started breaking ground on September 11, 1941. It was completed about 5 months later on April 1, 1942 60 years later the pentagon would be subject to the worst attack on American soil since Pearl Harbor. The Pentagon contains its very own branch of law enforcement known as the United States Pentagon Police and has a Jurisdiction of over 280 acres that encompass the Pentagon as well as the Pentagon itself. The pentagon contains no marble flooring because Italy was the biggest exporter of marble at the time and well, we were at war with them. They weren't about to sell us marble. lol. Guys I am still working on this project furiously. Please do not criticize me yet. I still need to do the hallways the underground parts, the land, and alot of stuff to finish this off. I will update as I get closer to finishing.
