Where 1776 fits
Why 1776 is special
1776 is a date that became a slogan. The Continental Congress approved the Declaration of Independence on 4 July, though the vote for independence itself was two days earlier and most delegates signed in August. The number appears on the Great Seal, in the design of the Washington Monument's height in feet, and in the name of One World Trade Center, whose 1,776-foot height was chosen deliberately.

1776 recurs deliberately in American design: it is on the Great Seal, and One World Trade Center was built to 1,776 feet specifically to invoke it. The date itself is slightly untidy — independence was voted on 2 July and most signatures came in August — but 4 July is what the Declaration was dated, and that is what stuck.

29 × 60 + 36 = 1776. Places are separated by a space on the tablet, with the higher place written first.
