Coventina is a goddess with a dedicatory well on Hadrian’s Wall .
The Well has long been buried and difficult to find on private land adjoining the fort at Carrawburgh. Now that ownership of the land has passed to Historic England, it should be opened up and restored, though there is no mention of the well in this BBC report about the acquisition of the site.
Material found in the well has been moved to a nearby museum and is discussed in that context in the video from Newcastle University which can be found HERE
