Plague stones are found across England, usually in the form of hollowed-out stones or boulders, relics of the medieval plagues. Stone boulders with hollowed-out depressions, or sometimes the bases of crosses, were filled with vinegar and placed at or near parish boundaries. Vinegar was used as a disinfectant in the hope that the community could buy food and other goods without fear of contagion. Residents placed coins in the vinegar-filled hollows to pay outsiders for goods or food left by the stone, believing that might halt the spread of the deadly disease.
