Hyssington is a parish in the South-Eastern corner of the historic county of Montgomeryshire in Wales and borders the county of Shropshire in England. It is now within the area of the Church Stoke community council in Powys. It is dominated by Corndon Hill. The church which is in the Diocese of Hereford lies just the north of a small village and is sited just to the west of a medieval Motte-and-bailey castle. This area was also the source of late Neolithic and Early Bronze Age battle-axes and axe-hammers, made from picrite that were widely traded around 2000 BC.
