PATTERDALE, a chapelry, joint with Hartsop, in the parish of BARTON, WEST ward, county of WESTMORLAND, 7 miles (N. by E.) from Ambleside. The population is returned with Hartsop. The living is a perpetual curacy, in the archdeaconry and diocese of Carlisle, endowed with £200 private benefaction, £600 royal bounty, and £ 500 parliamentary grant, and in the patronage of the Earl of Lonsdale. The church is dedicated to St. Patrick. There is a small school endowed with £6 per annum. Patterdale lies along the upper reach of Ullswater, amidst scenery of a most sublime character, the view being bounded by a vast amphitheatre of mountains, which surrounds the lake. It is intersected by numerous' rills from the mountains, and by others flowing from the three tarns, Brotherwater, Hayswater, and Angle tarn, emptying themselves into lake Ullswater; at the head of the latter is an inn for the convenience of tourists, near which a large fair for sheep is held in October. There are several very productive quarries of fine blue slate in the neighbourhood.
