But were you a face in the crowd at one of them?
Did you dance to Mr Motivator at the Hartlepool leg of the Tall Ships Races or watch the Queen visiting Hartlepool in 1977?
Did you watch the Christmas lights being switched on in 2013 or turn out to see Princess Anne in 1973.
We have put the spotlight on the crowds in this feature so have a look and see if you can spot someone you know.
