Schools, shops and pubs have hosted great events and the Hartlepool Mail’s photographers have been there to record them.
We found these archive photos from an Irish bar in town, and a theme day at Grange Primary School.
And we also have a creative day at Horden Cotsford School.
Take a look and see if these scenes bring back wonderful memories.
