Cricklade is a town and civil parish on the River Thames in north Wiltshire, England, midway between Swindon and Cirencester. It is the first downstream town on the Thames. The parish population at the 2011 census was 4,227. History Cricklade was founded in the 9th century by the Anglo-Saxons, at the point where the Ermin Way Roman road crossed the River Thames. It was the home of a royal mint from 979 to 1100; there are some Cricklade coins in the town museum. The Domesday Book of 1086 records a settlement at Crichelade, with a church, and at the centre of a hundred of the same name. Anglo-Saxon fortification Cricklade is one of thirty burhs (boroughs, i.e. fortresses or fortified towns) recorded in the Burghal Hidage document, which describes a system of fortresses and fortified towns built around Wessex by King Alfred. Recent research suggests these burhs were built in the short period 878–879 to defend Wessex against the Vikings under Guthrum, and to act as an offensive to the Viking presence in Mercia. Cricklade was an important part of these defences, being a short distance down Ermin Way from Cirencester, where the Vikings made their base for a year. According to the Anglo-Saxon Chronicle, completion of this system precipitated the retreat of the Vikings from Mercia and London to East Anglia in late 879. The square defences of the fortification have been excavated in several places on all four sides since the 1940s, possibly making them the most extensively sampled fortification of the period. In the initial phase, a walkway of laid stones marked the rear of a bank of stacked turfs and clay which had been dug from three external ditches. In the second phase, the front of the bank, which after only a short time probably became degraded, was replaced by a stone wall. This wall enclosed the defences on all four sides, considerably strengthening the defensive capabilities of the burh. It has recently been suggested the stone wall was inserted in the 890s. Other burhs of the Burghal Hidage were also strengthened with stone walls, which suggests this was part of a systematic upgrade of the defensive provisions for Wessex, ordered by the king. The third phase is marked by systematic razing of the stone wall, which was pulled down over the inner berm (the space between the wall and the inner ditch). The stones were
