Taken at the Archives of the United States of America, which houses the Declaration of Independence, the Constitution and the Bill of Rights, among other documents precious to the US. These two bronze doors, which each weigh 6 1/2 tons and measure 38 feet 7 inches high, almost 10 feet wide and 11 inches thick, guard the Constitution Avenue entrance.

I'd like to rework this, but simply don't have time at the moment (was lucky to have been able to rush down there and try to get some shots).
