Largely unaffected from the turbulent political events following the demise of the Western Roman Empire, the importance of watermilling continued to grow under the new Germanic lords. The sharp rise in numbers of early medieval watermills coincided with the appearance of new documentary genres (legal codes, monastic charters, hagiography) which were more inclined to address such a relatively mundane device than the ancient urban-centered literary class had been. This partly explains the relative abundance of medieval literary references to watermills compared to former times.
The quantitative growth of medieval evidence appears to be more than a mere reflection of the changing nature of surviving sources. By Carolingian times, references to watermills in the Frankish Realm had become "innumerable". At the time of the compilation of the Domesday Book (1086), there were an estimated 6,500 watermills in England alone.
By the early 7th century, watermills were well established in Ireland, and began to spread from the former territory of the empire into the non-romanized parts of Germany a century later. The introduction of the ship mill and tide mill in the 6th century, both of which yet unattested for the ancient period, allowed for a flexible response to the changing water-level of rivers and the Atlantic Ocean, thus demonstrating the technological innovativeness of early medieval watermillers.

The following list comprises stray finds of early medieval millstones. Note that there is no way to distinguish millstones driven by water-power from those powered by animals turning a capstan. Most, however, are assumed to derive from watermills.
