FBI Building
More than just a historical monument or the seat of any single administration of the federal capital, the seat of the Federal Bureau of Investigation (or as it's more commonly known, the FBI Building) is a real symbol in the heart of Washington. Unfortunately, it's always closed to the public (and it's easy to understand why!), We still love its famous facade, with huge American flags hanging proudly. An institution at number 935 Pennsylvania Avenue, not to be missed.
