What treasures have been found during the high-speed railway construction in the UK?

Treasures unearthed by hundreds of archaeologists so far during work on the planned HS2 train line have been shown exclusively to the BBC.

The 450,000 objects, which are being held in a secret warehouse, include a possible Roman gladiator’s tag, a hand axe that may be more than 40,000 years old and 19th century gold dentures.

The finds were uncovered during construction work on the HS2 railway, which is being built to connect London with northern cities in the UK.

The future of many objects, including whether they will stay in storage or be displayed, is still undecided, along with their ownership.
