LANGLEY (ABBOT'S), a parish in the hundred of CASHIO, or liberty of ST-ALBAN'S, county of HERTFORD, 1 mile (E. by S.) from King's Langley, containing 1733 inhabitants. The living is a discharged vicarage, in the archdeaconry of St. Alban's, and diocese of London, rated in the king's books at £15, endowed with £200 private benefaction, and £200 royal bounty. Sir J. Filmer, Bart, was patron in 1821. The church, dedicated to St. Lawrence, is partly Norman, and partly in the later style of English architecture; it has a square tower surmounted by a short spire, and contains some handsome monuments, and other sepulchral memorials. The Grand Junction canal passes through the parish. Nicholas de Breakspear, who first instructed the Norwegians in Christianity, and the only Englishman ever raised to the popedom, was born in this parish, though the place from which he took his name is situated in the adjoining parish of St. Michael: he assumed the title of Adrian IV., and was poisoned in 1159, in the fifth year of his pontificate, by a citizen of Rome, whose son he refused to consecrate bishop.
