White Grit is a small, scattered village beneath Corndon Hill in Powys, Wales, directly on the border with (and partly in) Shropshire. The nearby village of Priest Weston, despite being in England, actually lies to the west of White Grit. To the east is the A488 road. The nearest town is Bishop's Castle.
White Grit lies in the community of Church Stoke (the small parts in Shropshire are in the civil parishes of Chirbury with Brompton and Worthen with Shelve). Adjoining is a hamlet called The Marsh. There is a stone-built Methodist chapel in White Grit, no longer used as a place of worship, and a corrugated-iron chapel, both of which are marked on Ordnance Survey maps.
