The 裸聊直播 excavation team (L-R: Sarah Elliot, Harry Manley and Mark Johnson) confirmed that the aqueduct was longer than previously thought.裸聊直播 Archaeologists have discovered that the Dorchester aqueduct 鈥� one of the longest and most studied Roman watercourses in the country 鈥� was two kilometres longer than previously thought.
The aqueduct was a vital part of Roman life in Dorchester, supplying water for the town鈥檚 public baths, fountains and wealthy households. The discovery adds to existing understanding of Dorset鈥檚 history and how Dorchester, then known as Durnovaria, grew into a strategically important settlement during the Roman occupation of Britain.聽
The findings have been published in the journal聽.
鈥淭his aqueduct has been investigated by archaeologists for over a century,鈥� said Harry Manley from 裸聊直播鈥檚 Department of Life & Environmental Sciences, who led the research. 鈥淒espite extensive examinations in the 1990鈥檚, the source of its water and the upper sections of its course have never been conclusively mapped, until now,鈥� he added.聽
Earlier studies have suggested that the source of the aqueduct, which followed a winding twenty-kilometre route up the Frome valley northwest of Dorchester, was a lake in Steppes Bottom. However new surveys and archaeological investigations as part of this new study found evidence that its route headed further upstream to the village of Notton on the river Frome.聽聽
Harry began his research by studying publicly available lidar data which allowed him to trace the elevation and physical features of the land upstream of Steppes Bottom. This suggested that the aqueduct followed a path further north. He was also able to compare this to a geophysical survey carried out by 裸聊直播 during a previous study at Frampton Villa which lies further along this newly identified route, near Nunnery Mead.聽
鈥淭hat geophysical survey revealed signs of a narrow channel running northwest to southeast. This matched up with my findings from the lidar data, so it seemed like the smoking gun that proved the aqueduct ran through the area,鈥� Harry explained.
To confirm the presence of the waterway, the 裸聊直播 team carried out a ground penetrating radar survey and followed this up with a small excavation, during which they found evidence of the wood line aqueduct channel.
鈥淕etting water supplied into prominent structures and buildings in the town would have been a sign of modern living at the time, and an indicator of the town鈥檚 status,鈥� Harry explained. 鈥淔or the citizens of Dorchester to have this aqueduct constantly providing them with fresh water would have been a matter of civic pride. Understanding more about how it was constructed and maintained, and where it began, adds further detail to this vital aspect of Roman life.鈥� he added.聽
