A collection of metal Iron Age and Roman-era artifacts unearthed by a metal detectorist on an island in Wales has been declared national treasure.

Ian Porter made the discovery in 2020 while exploring pastures and a spring on Anglesey, located off the western coast of Wales’ mainland, according to a statement from Amgueddfa Cymru — Museum Wales.

“I was so excited when I found these items,” Porter said in the statement. “To think that the last person who touched them lived almost two thousand years ago and it shows some of the history of the island.”
