Townships in Montgomeryshire are divisions of the ancient parishes of the county of Montgomery. In 1539 townships were grouped together in Hundreds. The Townships which were recognised were based on the older Welsh divisions of Tref, or plural Trefi, which had formed the Welsh administrative districts of the Commote. Not all of the former Tref were recognised and some smaller trefi were amalgamated into larger townships. A township was allocated to a particular parish—that is, one of the [civil] parishes of Wales, the predecessors to today's communities of Wales. The townships were recognised as administrative districts, rather than the parishes.

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.
