Gadebridge Roman Villa, alternatively known as Gadebridge Park Roman Villa, is a ruined Roman villa in Hemel Hempstead, Hertfordshire, England. 
Excavation.
A chance discovery in 1962, it was excavated in 1963-68 under the direction of David S. Neal. A second excavation took place in 2000, also under the direction of Dr Neal.
History.
The site may have begun as a pre Roman farm, but after the Roman invasion of AD 43 its proximity to the Roman city of Verulamium seems to have precipitated its development into a sort of spa and resort. From the Antonine Period, c. 138 AD, stone buildings were added, and around 300 AD a large swimming pool, the biggest in Roman Britain after the one at Bath were built.
The site may have been leveled around AD 350 possibly because of its owner's support for the usurper emperor Magnentius. It returned to agricultural use and was used for cattle pens.
Conservation.
The villa is situated in Gadebridge Park. Since the excavations the site has been scheduled and is under grassland.
Artefacts from the villa are held by the Dacorum Heritage Trust.
