The corn mill (part of the Felin Isaf complex, nprn 85444)
uses two French burrs and it is housed in a rectangular rubble building of two-and-a-half storeys under a slated roof. It has boarded cambered entrances and leaded windows. The eighteen foot (5.5 metre) diameter iron-framed pitchback waterwheel is fed by a leat running west to east that is carried over the approach lane by a segmental-arched rubble bridge.
