Safeguard ABM radars and the back of a one dollar bill
I was watching a video about the Safeguard ABM system:

Which was interesting but the thing that struck me was that pyramidal radar building in North Dakota:
Which reminded me of this:
I couldn't find an exact size of the building and it's hard to guesstimate but the round antenna arrays on each face are supposed to be about 13 feet in diameter. However there are two concentric circles so is the smaller circle 13 feet across ? That would make the building something over 60 feet tall - so much smaller than the great pyramids in Egypt - but still quite impressive.
Here are a few links to info / photos on the ND pyramid:
