WALNEY (ISLE-of), a chapelry in the parish of DALTON-in-FURNESS, hundred of LONSDALE, north of the sands, county palatine of LANCASTER, 5 miles (S. W.) a lighthouse on its southern extremity, a short distance north from which is a rocky islet, termed the Pile of Fouldrey, ie., the island of fowls, where are the venerable ruins of a strong castle, built by an abbot of Furness. There are several other small isles in the group, the principal of which is Old Barrow, lying between this and the main land, opposite the small village and port of Barrow. On Walney are some remarkable intermitting springs of fresh water. It is stated to have been once covered with wood, of which it is now extremely barren. West, in his "Antiquities of Furness," describes it as lying on a bed of moss, which is found by digging through a layer of sand and clay, and in which trees have been discovered. To prevent the encroachments of the sea, the abbots of Furness kept up a dyke, which, since the dissolution, has been neglected, and the sea has made considerable inroads.
