Two pits were found during work to convert an above ground air-raid shelter into a classroom. The fill of the earliest pit consisted of bottles, china, pottery and glass of 18th century date. On the basis of this evidence the pit is thought to have been a rubbish pit at the rear of a property occupied by an apothecary or doctor. The other pit was far larger and cut the rubbish pit: this is likely to have been a cesspit or septic tank.
