Rock, Northumberland Rock, Northumberland Rock is a village in Northumberland, England about north of Alnwick. The single street has on one side cottages and gardens; on the other, an ornamental lake. At the end is a little Norman church; and beyond that, the battlements and towers of Rock Hall. The sundial and the inscribed stone in the end wall of the schoolroom were originally part of a residence of the Salkelds which stood on the site. The Hall was then their seat – their coat of arms still remains above an old, blocked doorway to the right of the modern entrance. Later
