Hexham (ˈhɛksəm ) is a market town and civil parish in Northumberland, England, on the south bank of the River Tyne, formed by the confluence of the North Tyne and the South Tyne at Warden nearby, and close to Hadrian's Wall. Hexham was the administrative centre for the Tynedale district from 1974 to 2009. In 2011, it had a population of 13,097. Smaller towns and villages around Hexham include Corbridge, Riding Mill, Stocksfield and Wylam to the east, Acomb and Bellingham to the north, Allendale to the south and Haydon Bridge, Bardon Mill and Haltwhistle to the west. Newcastle upon Tyne is to the east and Carlisle to the west. The name Hexham derives from the Old English Hagustaldes ea and later Hagustaldes ham from which the modern form (with the "-ham" element) derives. Hagustald is related to the Old High German hagustalt, denoting a younger son who takes land outside the settlement; the element ea means "stream" or "river" and ham is the Old English form of the Modern English "home" (and the Scots and Northern English "hame"). Hexham Abbey originated as a monastery founded by Wilfrid in 674. The crypt of the original monastery survives, and incorporates many stones taken from nearby Roman ruins, probably Corbridge or Hadrian's Wall. The Anglo-Saxon Chronicle (Manuscript D: Cotton Tiberius B IV) records the murder of King Ælfwald by Sicga at Scythlecester (which may be modern Chesters) on 23 September 788: This year Alfwald, king of the Northumbrians, was slain by Siga, on the ninth day before the calends of October; and a heavenly light was often seen on the spot where he was slain. He was buried at Hexham in the church. Her wæs Alfwald Norðhymbra cyning ofslægen fram Sigan on .viiii. Kalendas Octobris, 7 heofonlic leoht wæs lome gesewen þær þær he ofslægen wæs, 7 he wæs bebyrged on Hagustaldesee innan þære cyrican. Like many towns in the Anglo-Scottish border area and adjacent regions, Hexham suffered from the border wars between the kingdoms of Scotland and England, including attacks from William Wallace who burnt the town in 1297.
