Water mill

During Phase 4 (700-900 AD) a substantial mill with a large oak framework was established over Southern mills 3 and 4. A SW-NE millrace expands into a shallow millpond (Wth 8-10m; L c. 20m; D 0.75m) that was filled largely with grey/brown silt deposits. At its NE edge boulder clay deposits formed a dam leading to the undercroft (dims 3m NE-SW; 2m NW-SE) that was formed by large oak base-beams, all of which survived except that at NE. A plank from the NW side-beam provided a C14 date of 763-895 cal. AD, and there were three other planks from the side-walls within the undercroft area. A second beam inside that at SW may have been for the bridge-sole. The tailrace ran SW-NE parallel with and just S of another channel that cut a major Phase 2 NE-SW ditch, but both channels were intended to function together.
