Right below the beavers and flour barrels on New York City's official seal is the year 1625.
There’s just one problem: Most historians say the year has hardly any historical significance.
The first settlers arrived in what would become part of New York City on a Dutch ship as early as 1623; some say 1624. The Dutch “purchased” Manhattan in 1626. The first charter was granted in 1653.
And the most notable event of 1625? Dutch settlers moved their cattle to Lower Manhattan from Governors Island. [Link]
