Coal pit hills

I lived in Oldham during the 50s and attended Werneth County Primary. Nearby was a feature known as the coal pit hills, bounded on one side by Chamber Road. I think that it was probably an unsightly sl*g heap, but to children it was a wonderful and exciting place to play. Needless to say, we were strictly forbidden by the school to play there, a rule that was enthusiastically ignored. Does anyone else remember hiding up in the hills and running down the slopes? What were the big flat stones on top and when did the pit close?

Also, does anyone remember the air raid shelters in the boys' playground?

Would love to hear from anyone else who can give me more information or share their memories.

I Rember the pit hills. We used to play there as kids although we were not supposed to.
I lived on Hardman st . across manchester rd  from chamber rd. Man we used to get dirty.
Live in Canada now.

I went to Werneth primary and junior schools between 1943/1952 and remember the coal pit hills off Chamber Rd well. When I first saw them the winding tower was still in position. I like so many children loved to play on them, but you had to be very careful. I also used to play football for Werneth School just below the hill called Red Flats, you hated falling over as the ground was nothing but gravel.
I also remember the air raid shelters in the boy’s playground of the junior school, there also used to be shelters in the girls playground.
What happy memories
