The Mold Cape is 3,700 years old and is described as one of the most important finds from the Bronze Age.
Now, the gold cape is on a tour of Wales, on loan from the British Museum in London.
It was discovered in Mold, Flintshire, in 1833 when workmen discovered a skeleton in a grave at the centre of a circular burial monument.
Despite its age, experts say they are continuing to learn more about life in prehistoric Europe.
It is being shown at the National Museum, Cardiff, from 2 July to 4 August.
It will also be on show at the Wrexham County Borough Museum from 7 August to 14 September.
