A hole new way of looking at things

Oh dear! A very small hole in our playground has turned into a bigger one.

Is it the cellars of the old Parke School* which once stood on the site? 

Or is it part of the old air raid shelter which once held 2000 people, and which is said to stretch to the Leisure Centre?

Don't worry - it's securely fenced off. But most intriguing......

* Not Old Park School, but Parke School
