the village of Alnham is situated near the source of the Aln, nine miles N. N. W. of Rothbury, and has evidently been a place of some importance in ancient times. To the south of the village is Black or Blake Chesters, which was occupied as a station by the Romans, and on the summit of a hill, a mile west of Alnham, is a semi-circular encampment, defended by two outward ramparts and a deep fosse, with an inner circle of uncemented stones. In the vicinity of the vicarage there are the vestiges of an old border castle, which seems to have been, at one time, a place of great strength, and about four years ago, there was discovered in the glebe field, on the north side of the tower just mentioned, a portion of a paved road, supposed by many to have been constructed by the ancient Britons. the church, dedicated to St. Michael, is a very ancient structure in the style of architecture which prevailed during the early part of the reign of Edward III, though some of the windows are of more modern construction. The parish register commences in 1688. The living, a vicarage in the archdeaconry of Lindisfarne and deanery of Rothbury, is valued in the Liber Regis at £3 17s. 1d. ; gross income £130. Patron, the Duke of Northumberland; vicar, the Rev. George Selby Thompson, M.A. the vicarage is a square embattled tower of the same date as the church, and having become very much dilapidated, subsequent to the great rebellion, it was restored by the patron of the living, in 1844. Probably this tower was the property of the Umfravilles of Harbottle Castle, as well as Rothbury and Elsdon Towers, which still bear their arms. The river Aln rises in the hills west of the village, and pursues an easterly direction towards Whittingham.
