Clwyd-Powys Archaeological Trust carried out a series of investigations at Beacon Ring hillfort in 2017–18, with funding from Cadw. Work included topographic and total station survey, geophysics, auger sampling, and trial trenching. The surveys produced a revised plan of the earthworks and examined the entrances, while auger sampling and excavation provided new evidence for the construction and later modification of the ramparts and ditches. Although no clear dating evidence or occupation layers were identified, the results indicate a complex sequence of use and later disturbance, adding to our understanding of this prominent monument on the Montgomeryshire border.
