Sofia - Bulgarian archaeologists have discovered a large gold chain made 4,000-6,000 years ago, in the Bronze Age, media reports said Tuesday.

The 1.5-metre chain, made of 320 links, was found along with gold and silver artefacts in a grave in southern Bulgaria.

The find may shed more light on the ancient period of which there is very little knowledge, the head of Bulgaria's National Historic Museum said. (dpa)
