Workers repairing Chester’s city walls discovered previously undocumented remains of a Roman gate tower.

Archaeologists believe that the tower was one of a pair that once flanked the northern entrance to the Roman fort on which the city was founded. The remains were found under a set of 19th century steps, which were declared unsafe. The experts also found evidence of the wooden gateway that preceded the stone tower and of the later medieval gateway which replaced it. Another discovery in the area was of a chamber to the west of the steps, which is thought to be all that remains of two cottages built against the walls in the 18th century. The Medieval North Gate, which also housed a gaol, was demolished in 1808 and replaced with the current structure soon after.
