Big birthday celebrations are under way for Peterlee; because it's 75 years old.
The town has certainly had plenty of big-name employers in its midst from Caterpillar to Fisher Price and Walkers Crisps to Dewhirst.
There's been royal visits and days to celebrate.
Why not have a look back yourself at some of the town's factories which hold a place in the Sunderland Echo archives.
