Castle Head is a rocky mound rising out of the marshes at the mouth of the River Winster, about a mile north-east of Grange and immediately east of Lindale. The house was built in 1795 by John Wilkinson, a local man who had become one of the great ironmasters of the industrial revolution with forges in Shropshire, Staffordshire and Wales. He died in 1808 and was buried on the island at the time of Turner’s sketch, though his body was later removed to Lindale. The house survives (somewhat enlarged) to this day, serving as a field study centre. Turner’s view is from the access road across the marshes, looking due south past Castle Head to Holme Island off Grange. He appears to have been struck by the corn growing next to the sandy estuary, and would possibly have been surprised today by the extent to which the land has been drained and cultivation extended. As previously observed by this writer, Turner has managed to record evening light and calm conditions with great economy.
