two adjoining towns of England, county of Devon, on the left bank of the Plym, 4 miles N.E. of Plymouth, and 213 W.S.W. of London. Plympton St Mary, which lies to the N.W. of the other, contains no notable building, except the old lichen-tinted church, standing with its demons' heads and other grotesque ornaments in a lawn-like churchyard. Pop. of the parish (1851) 2815. Plympton Earle, or Plympton St Maurice, contains the ruins of a castle famous in the wars of King John and of the Commonwealth, crowning a knoll, near which stand the old granite church and the quaint grammar school with its high roof and piazza. The town contains many old houses, some of them raised on arches; and a venerable guildhall, bearing the date 1671. Plympton Earle was the birthplace of Sir Joshua Reynolds. Pop. (1851) 833.
