Wigan is well known as one of the key industrial towns of nineteenth-century Lancashire. However, there is increasing evidence to demonstrate that Wigan also has a rich Roman heritage. Whilst some remains and artefacts were discovered during construction works in the nineteenth century, the most remarkable evidence for Roman activity in the town arose from archaeological excavations carried out since the 1980s in the Millgate area. In particular, the remains of a second-century bath-house were discovered during excavations by Oxford Archaeology North in 2004-5, whilst further excavations in 2008 provided new evidence for Roman activity in the first centry AD. The exciting findings from these excavations are summarised in this booklet, which presents th latest information on Roman Wigan.
