Discovery and Excavation
The Roman baths tucked beneath the A1(M) in Welwyn, Hertfordshire are a scheduled ancient monument, part of the Dicket Mead Roman villa complex.
Discovered in 1960 by Tony Rook, excavations by the Welwyn Archaeological Society revealed a bath complex within a larger villa. This bath house is preserved under the motorway embankment within a steel vault. The villa dates from the early third century and fell out of use in the mid-fourth century.
Visiting the Site
The site is open to the public on Saturdays, offering family-friendly, hands-on learning and fascinating experiences up close with real archaeology.
The opening season runs until November 28, 2026 and re-opens March 6, 2027.
