Hidden Roman buildings could be unearthed as a week-long dig begins in Herefordshire on Saturday.
Viewers can vote for the dodecahedon as their favourite item
Archaeologists are looking for a Roman bridge, road and settlement at the River Wye close to Hereford.
County archaeologist Dr Keith Ray said his team would also be looking for evidence of a river crossing and a port for the nearby town of Kenchester.
The dig will be shown live on Monday and Tuesday evening as part of Channel Four's Big Roman Dig.
"This is very exciting as it is a rare opportunity to look closely at such an important historic Roman site," Dr Ray added.
The programme will also feature the Roman dodecahedron, found in Credenhill and housed in Hereford Museum.
Viewers will be invited to vote for their favourite item from ten pieces shown from across the country.
Historians and scientists have been unable to agree what the dodecahedron was used for.
