The monument took 13 years to build, commemorating the thirteen original colonies. Its total height in metres is 169, which is thirteen squared. And the capstone is a block of aluminum, element number thirteen!
If the sum of the integers in a number is divisible by three, that number will also be divisible by three. I’ve seen the proof, but don’t remotely remember it.

As a kid, I climbed those stairs to the top. Back then there were 4,319 steps… We almost all took the elevator down.
