French Mill and Tidal Barrier

Three storeys plus attic, built of local limestone, rendered, with a slate roof. Range of five windows in each of the main elevations, facing E and W, and a range of two windows in the gable ends. The attic is lighted by single windows in the gables. Small windows with cambered brick arches and 16-pane tilting casements, all restored. External steps lead down to the basement level at the S end. Several remedial tie rods stretch across the mill and are anchored into external tie plates. The building is now entered through the N extension wing. The Tidal Barrier lies across the estuary of the Carew River about 300 m W of Carew Castle. A stone faced causway with a clay core about 150 m long with central floodgates and spillway at the N end. When functioning the barrier impounded a pool of over 9 hectares and there was an available head of water of 3.3 m.

The top floor is the bin-floor; beneath it is the stone-floor; and the ground level is the meal-floor. The machinery has been restored with the exception of the N wheel. In the N extension is the reception area, with an audio-visual room in its loft.
