AMESBURY, a parish (formerly a market-town) in the hundred of AMESBURY, county of WILTS, 7 miles (N.) from Salisbury, and 78 (W.S.W.) from London, containing 810 inhabitants. This place, anciently called Ambresbury, derives its name from Aurelius Ambrosius, a descendant of the Romans, who is said to have assumed the purple in Britain towards the decline of the Roman empire, and who headed the Britons in several attempts to repel their Saxon invaders. A monastery for three hundred monks is stated to have been founded here by Ambruis, a British monk, or, more probably, by Ambrosius, which was destroyed by Gurthurm, or Gurmundus, a Saxon chief. After the conversion of the Saxons to Christianity, a synod was held here, in the reign of King Edgar, to adjust the differences which existed between the regular and the secular clergy, which had been previously discussed in an assembly held at Calne. About 980, Elfrida, widow of the same king, founded here a nunnery of the Benedictine order, which she dedicated to St. Mary and St. Melorius, a Cornish saint, in expiation, it is supposed, of the murder of Edward, her step-son, at Corfe Castle. In 1177, the abbess and nuns were expelled, on the ground of incontinence; and Henry II. made it a cell to the foreign abbey of Fontevrault. Queen Eleanor, widow of Henry III., assumed the veil in this convent, where she died in 1291. It was at length made denizen; and, at the dissolution, its revenue was valued at £558. 10. 2. The mansion called the Abbey, which now occupies the site of the nunnery, was, after the French revolution, at the close of the last century, appropriated for several years to the use of a society of nuns from Louvaine in Flanders, who afterwards removed into Dorsetshire. The town is situated in a small valley, on the bank of the Upper Avon, and consists of two streets: it is neither paved nor lighted, but is well supplied with water. The market, formerly held on Friday, has been discontinued: fairs are held on the 17th of May, 21st of June, and 21st of December. Constables and other officers are appointed at the court leet of the lord of the manor. The living is a perpetual curacy, in the archdeaconry, of Wilts, and diocese of Salisbury, endowed with £400 private benefaction, and £700 parliamentary grant, and in the patronage of the Dean and Canons of Windsor. The church, which was formerly convex tual, is a very ancient building, probably of Saxon architecture; it is dedicated to St. Mary and St. Melorius, and has recently been completely repaired: it is warmed by a pair of very handsome stoves, which cost £189, and were presented by Sir Edmund Antrobus, Bart. There is a place of worship for Wesleyan Methodists. An English school for twenty boys was founded and endowed, in 1677, by Mr. John Rose; and a school for teaching fifty children to read was endowed with an estate left by Mr. Spratt: a charity school for clothing and instructing fifteen boys andfifteen girls, and a National school, are supported by, subscription. A fund is also appropriated to the apprenticing of children. Westward from the river there is au ancient encampment, with a vallum and deep fosse, occupying an area of forty acres, commonly attributed to Vespasian, but undoubtedly of British origin: the road from Amesbury to Warminster is cut through its rampart. Within two miles is Stonehenge, a remarkable and well-known relic of British antiquity.
