  • Built during World War II, it is a building of cyclical proportions. The pentagonal form is a resumption of that of many forts, castles and fortified citadites (see Palmanova in the province of Udine). It is 24 meters high and contains about 28 km. corridors inside that contains about 40,000 people who work there. You can take guided tours, but it is important to book well in advance.

  • There are Starbucks and areas where you can eat, the coffee and food is very expensive, so you better eat at home before visiting the pentagon. Safety here is extremely so don't try anything strange that makes your journey is concluded. Believe me, you will enjoy a lot of this experience.
  • If the people only knew how many Pentagon buildings there are and have been that perfectly line up with this one around the world.. It also lines up with Stonehenge..
