MALLERSTANG, a chapelry in the parish of KIRKBY-STEPHEN, EAST ward, county of WESTMORLAND, 3 miles (S. by E.) from Kirkby-Stephen, containing 243 inhabitants. The living is a perpetual curacy, in the archdeaconry and diocese of Carlisle, endowed with £600 private benefaction, and £600 royal bounty, and in the patronage of the Earl of Thanet. The chapel, having fallen to ruin, was repaired in 1663, by the celebrated Countess of Pembroke, who endowed it with lands near Sedbergh in Yorkshire, then worth £ 11 a year, on condition that the curate should teach the children of the dale to read and write, in a room over the west end of the chapel; and in compliance therewith about thirty are instructed. At Castlethwaite are the ruins of a square tower, that formed part of Pendragon castle, built by liter Pendragon, hi the time of Vortigera, the walls of which are twelve feet thick. It was at one period the seat of the Lords de Clifford, and was burned by the Scots about the year 1541, but was completely repaired in 1661, by the Countess of Pembroke, who also built the bridge across the Eden, and erected the stone pillar on the hill called Merrill's Seat. The castle was dismantled by the Earl of Thanet in 1681; near it is an ancient fortification, surrounded by a moat and vallum. At the southern extremity of the chapelry rises the lofty mountain called Wild Boar fell.
