Llyn Cerrig Bach

Llyn Cerrig Bach is a small lake located between Rhosneigr and Valley in the west of Anglesey [1]. Whilst it is not one of the largest lakes on the island (around 1.8 acres), its claim to fame is the group of over 150 Iron Age metal objects discovered there in 1942, apparently placed in the lake as votive offerings [1]. These finds are considered to be one of the most important collections of La Tène style metalwork, or Early Celtic art discovered in the British Isles, and the most important in Wales [1]. The discovery was made by William Owen Roberts, head groundsman of RAF Valley, when ground was being cleared for a runway extension [1]. This involved spreading peat over the sandy ground, and the items were discovered during the extraction of peat from the Cors yr Ynys bog on the southern margin of Llyn Cerrig Bach [1]. The first object to be found was an iron gang chain, used for slaves [1].
