I am intrigued by Harrison Park. I walk the dog there every day and have visited there since the late 1940's. However it seems evident that the "hill" is artificial. It sticks out of the flat surroundings as if planted there, moreover it contains what appears to contain building rubble, bits of iron pipework stick out of it and also concrete.
I wonder if it is compose of the remains of an earlier building on the site, or if it contains war rubble (can't be second World War though).
Does anyone have its History
