Llyn Cerrig Bach

Llyn Cerrig Bach is a small lake on Anglesey, Wales, where approximately 180 Iron Age metal objects were discovered in 1943 during construction of RAF Valley airfield. The assemblage includes 11 swords, 8 spearheads, parts of a parade shield, and equipment from up to 22 chariots, deposited as votive offerings between c. 300 BC and AD 60. It represents the most important British example of Celtic ritual deposition of prestige metalwork into sacred waters, a practice described by Caesar. The collection is held at the National Museum of Wales in Cardiff.
