The prehistoric Beacon Ring hillfort, south of Welshpool, Powys, Wales. E II R stands for Elizabeth II Regina.
52.6449° N, 3.0880° W

The circular shape of this prehistoric hillfort is still clearly visible on Long Mountain. The fort was built and first occupied between the later Bronze Age and the early Iron Age – after 1000BC and before the arrival of the Romans c.50AD

In Welsh the fort is called Caer Digoll (Caer = fort), which came from the Welsh name for this ridge, Cefn Digoll (digoll = complete, unbroken). [...]

The fort’s English name refers to a beacon which was last lit at the site in June 1887, celebrating Queen Victoria’s Golden Jubilee (50 years as monarch). A 1663 map of the Leighton Estate shows a pole with a fire-basket and ladder at what is called “The Beacon place”. Tarred rope was usually burnt in iron fire baskets of this kind as a signal at times of emergency. The plan of the Beacon Ring hillfort shown on this map is possibly the earliest depiction of a hillfort in Wales.

In 1953 the hillfort was planted with a mixture of pine and beech trees to pick out the letters E II R (for Elizabeth II Regina). This was to celebrate the Queen’s coronation but the effect is invisible, except to the few who fly over.

In 2008 the hillfort was acquired by the Clwyd-Powys Archaeological Trust. One of its priorities for the site is to remove the trees and to recreate the upland meadow which existed at the site until the early 1950s.
