1340 states its value was £37 13s. 4d. In the king's books (Henry VIII, early 16th century), it was valued at £3 7s. as a discharged vicarage. During the reign of Elizabeth, it was also £3 7s. It is part of a formal document written in 1597, by Henry, the ninth Earl of Northumberland, to Thomas Percy. For many years this Thomas Percy, one of the leaders in the Gunpowder Plot, was constable of Alnwick Castle, and auditor and commissioner to the Earl. Notice of Alnham Church is found in Tate's 1866 The History of the borough, Barony and Castle of Alnwick, Vol. I. It is dedicated to St. Michael, the most popular Saint in north Northumberland, with no less than eight churches in the Archdeaconry of Lindisfarne dedicated to him. Architecture Although the building appears to date from about 1200, older features include Saxon quoins within the nave. The church is constructed in the style of architecture which prevailed during the early part of the reign of Edward III (mid-1300s), though some of the windows are of more modern construction. Building features include a bell-cot, a lower chancel, a porch, and a three-bay arcade. There was a north aisle in previous centuries. There are north and south transepts, though only the south one is part of the original construction. The north transept was used as a Sunday school. The chancel has a Transitional arch. There are four buttresses at the west end and two at the north and south. Some of the ancient windows are preserved. The church restorers of the 18th century inserted a few sash windows, and in some minor matters otherwise impaired its integrity. Elements from 16th and 17th-century work include a porch and doorway. A strong roof was added in about 1840. In 1862, the church was described as having a rickety door and mildewed walls. The western end contained an Early Transitional single window. The rest of the window openings had been modernised and filled with common sashes, which were rotten, letting in wind and rain. The east end had a small square sash, such as is ordinarily provided for a scullery or any inferior office. Three of the pews were square, with a table fixed in the centre of each; a fourth formed three sides of a quadrangle that was occupied by a stove. Fungi abounded, and the pavement was sodden and damp.
