OK just in case you don’t know what the Pentagon is, it is the epicenter of America’s defense forces. It is the headquarters for the U.S. Department of Defense. It is one of the biggest office complex in the nation with about 6,500,000 sq ft. It is so big that the U.S. Capital can fit in just one of it’s five sides with plenty of space still available. The Chinese are so fond of the Pentagon that they built their own, but its not for the same use. Their Pentagon is actually a gigantic shopping mall dubbed the “Shanghai Pentagonal Mart”. The $200 million construction spans 70 acres which means it is already topping the actual Pentagon in size which spans only 34 acres. But the structure was completed all the way back in 2009 and is now the largest vacant building in Shanghai. According to the People’s Daily News the building has remained virtually empty since its completion because no one can navigate its confusing inner structure and also it’s apparent undesireable location. This kinda reminds us of the creepy Ryugyong Hotel -aka- “The Hotel of Doom” in North Korea which was never completed and remains incomplete and deserted today.
