Joseph Mallord William Turner

When turned with the gutter below the drawings, the lower sketch is to the north-east up the Fowey Estuary, with Polruan on the right. The upper view, inverted in relation to it, is one in a series of the blockhouses at Fowey and Polruan, on opposite sides of the estuary; it is detailed enough for the structure to be differentiated from the north front of the Polruan blockhouse, which survives largely intact, and presumably shows instead the south front of its equivalent on the Fowey shoreline, of which little remains.

The two drawings were probably made from about the same viewpoint, north of Readymoney Cove. The main view of the blockhouse on folio 37 verso (D08432) is similar. For other views in and around Fowey see under folio 5 verso (D08371).
