Back in the day, schools often had their own air raid shelters. A little bunker in a hillside such as this one Ha'penny Shelter
In Heyrod, Stalybridge, such a shelter was built behind the then school, now village hall. I can confirm its existence, having hesitated at the threshold with a match, as a child, but never dared venture beyond the first bend in the tunnel. The entrance was blocked up behind the new retaining wall but I was told a manhole exists in the field above which affords access to said shelter.
