The Chiseldon Cauldrons were discovered in November 2004 in a field to the south west of the village. It was a unique find: the largest group of Iron Age cauldrons ever to be discovered in Europe.
A metal detectorist had discovered the badly-corroded fragments of a bronze bucket and, on removing them from the ground, found he then had a much stronger signal beneath. A small hole was dug and about 25cm down an iron ring approximately 10cm in diameter attached to a curved surface was revealed. The site was closed down pending a decision on further action.
Initially, the find was believed to be either of medieval or later date, but material analysis of the bronze fragments showed that they were of Iron Age date. This caused considerable interest, and Wessex Archaeology, together with a conservator from the British Museum, carried out a dig in June 2005.
Excavations revealed a 2-metre diameter pit dug into the chalk into which a number of bronze and iron cauldrons - now thought to be as many as seventeen - had been carefully placed. Ox skulls had been placed above and below the deposit.
