Llyn Cerrig Bach

Llyn Cerrig Bach is a small lake located between Rhosneigr and Valley in the west of Anglesey, Wales.

The discovery was made by William Owen Roberts, head groundsman of RAF Valley, when ground was being cleared for a runway extension.

[2] Cyril Fox argued that the chain was evidence of human sacrifice by Druids as reported by Tacitus who writes that the Roman army landing on Anglesey "urged by their general's appeals and mutual encouragements not to quail before a troop of frenzied women, bore the standards onwards, smote down all resistance, and wrapped the foe in the flames of his own brands.

Once the chain had been identified, a search of the area produced a large number of other objects, mainly of iron but some of bronze or copper alloy.

In addition, blacksmith's tools, fragments of two cauldrons, iron bars for trading and animal bones were also found.
