Experts from Newcastle University are to begin excavating an internationally important Roman site in Cumbria.
The archaeological team is focusing on the site of a major discovery of Roman altars 141 years ago.
The site where the 17 altars were found now forms part of the Roman Maryport site at Camp Farm, which is owned by Hadrian's Wall Heritage.
It is hoped the dig, which will continue into July, will shed light on the nature of religion at the time.
Project leader, Prof Ian Haynes said: "The Maryport altars have been at the centre of international debate about the nature of religion in the Roman army for decades.
