The Mull has one of the last remaining sections of natural coastal habitat on the Galloway coast and as such supports a wide variety of plant and animal species. It is now a nature reserve managed by the RSPB.
According to Coxe, you will find three sea-water wells situated some 30 yards northwest of the ruins of St Medan's Chapel. "Sickly" children were immersed in the waters and a offering left in the chapel in the hope of a cure.
