Ireland’s beautiful Lough Swilly was the setting for a dramatic story which changed the life of a foul mouthed slave trader; John Newton In 1748, Newton, then a slave trader, was sailing to England when his ship was caught in a violent storm. When all hope was lost, he found refuge on the shores of Lough Swilly. Believing God had saved him he changed his ways and went on to pen one of the most famous and well loved songs of all time – “Amazing Grace”. The Amazing Grace Park is located beside the tourist office and a short walk along the shore takes you to The Amazing Grace Viewing Point.
