Ongoing excavations have revealed Roman ruins that were once part of a legionary fortress.

Archaeologists in England have discovered several Roman ruins buried next to a cathedral in Exeter.

The structures, which were built between A.D. 50 and 75, include a street and wooden buildings that were once part of a Roman legionary fortress, according to a statement.

The construction itself was likely part of a “long barrack building,” John Allan, a cathedral archaeologist with the University of Exeter, said in the statement.
