Surrounded on three sides by residential development, and on the fourth the car park at Cold Knap,…read morethis is the last place you'd expect to find an archaeological site. I'm sure it is completely ignored by its neighbours, and by the vast majority of people who visit Cold Knap beach in Barry. Nevertheless, here is Barry's oldest scheduled ancient monument, over 700 years old.
The site was known about in the early 1960's, when construction work on the Waterside Hotel unearthed some Roman remains, but no formal excavation was carried out. Another opportunity came with the demolition of the YMCA hostel in 1979 on the site immediately to the west, and this time a formal excavation was carried out.
To everyone's surprise, they found a major public building, dating from the late Third Century or early Fourth Century AD. A building of 22 rooms, arranged around a central courtyard, with cellars and what may have been a watchtower, were excavated. It is clear that the quality of building materials was high, with dressed stone and a tiled roof. After the excavation, the site was conserved, and a small viewing platform was built, complete with interpretation boards.
It's exact purpose is unknown, and it appears that the building was never completed as intended. The best guess is that it was intended as a sort of official guest house and possible storage facility for users of the Imperial Roman Post System, located by a small inlet, and opposite a known harbour on the English side of the Bristol Channel.
To-day, nothing remains much above the foundations, but you can clearly see the layout of all 22 rooms, including the cellar, and the area of the courtyard. The interpretation panels, though badly weathered, provide a helpful description, plan and a picture recreating what the building may have looked like.
The entrance is off the small footpath, immediately behind the public toilets at Cold Knap Terrace Car Park. In the summer, it's possible to take a quick look at this little piece of ancient history, before enjoying an ice-cream and a stroll along the promenade
