Welwyn Roman Baths is a minor section of Dicket Mead, a larger Roman villa that dates from circa 250AD. The villa is located 0.5 kilometres east of today’s Welwyn village, which was once home to a Roman settlement.

Before the A1 was built, the site was discovered in 1960 and excavated by the local archaeological society (M). Driving along the M1 at Junction 6 may make you completely oblivious that 9 metres below you sits the Welwyn Roman Baths, one of Hertfordshire’s most spectacular archaeological monuments, expertly maintained in a steel vault with a constant temperature of 10 degrees. A walk along an entranceway decorated with ancient Roman tiles leads to a tunnel constructed in the freeway embankment. Archaeologists believe there were at least four structures on the site, some of which have never been explored. The Welwyn Roman Baths were located at the end of one of these four main structures. Come have a look for yourself!
