The Whetstones are, or were, a stone circle beneath Corndon Hill in the parish of Church Stoke, Montgomeryshire, Wales, near the border with Shropshire, England.

[2] By 3000 BCE, the long barrows, causewayed enclosures, and cursuses which had predominated in the Early Neolithic were no longer built, and had been replaced by circular monuments of various kinds.

[7] The archaeologist Mike Parker Pearson suggests that in Neolithic Britain, stone was associated with the dead, and wood with the living.

[7] These Whestones were among five probable stone circles that are historically recorded as being within two miles of each other, largely in Shropshire but also stretching in neighbouring Powys.

"[12] In 1860, the antiquarian Robert William Eyton still referred to the Whetstones as a "remarkable monument",[13] but they were later stated to have been dug up, and the stones incorporated into a boundary wall, in about 1870.

[15] The remnants of the circle can still be observed from an adjacent field boundary, or from the northern summit of Corndon Hill.
