Today I got a nice postcard from the USA! The postcard shows an aerial view of the Pentagon, the headquarters of the Department of Defense. Named for its unique shape, it is located in Arlington, Virginia. Hosting about 26,000 employees, it has 340,000 square metres of office area. It was designed by George Bergstrom and was completed on 1943. The postcard is an official Postcrossing card, US-3197545. Thanks Nina!
