The Coggalbeg hoard

The Coggalbeg hoard is an Early Bronze Age hoard of three pieces of Irish gold jewellery dating to 2300–2000 BC. It was found in a bog at Coggalbeg, County Roscommon in 1945, and consists of a gold lunula and two small gold discs. It's thought that the objects were ritually deposited as an offering to gods. The lunula is of the "Classical" type, considered the earliest and finest of three types of lunula. Of the estimated 100 lunula known in Western Europe, some 80 originate in Ireland.

The priceless gold was first discovered by farmer Hubert Lannon. He found it in a bog while cutting turf and kept it at home. In March 2010, two men pleaded guilty to burglary and were given three-year suspended sentences. Working with police, curators from the National Museum’s Irish Antiquities Division found out that the jewelry had been left in a dumpster in Dublin. The police had hours to locate the dumpster before the trash would be collected. The detectives waded through a dumpster and found the treasures. The necklace and two discs are among the most important archaeological discoveries in Ireland for many years.
