The Abbey Church of St Mary the Virgin, Tewkesbury–commonly known as Tewkesbury Abbey–is located in the English county of Gloucestershire. A former Benedictine monastery, it is now a parish church. Considered one of the finest examples of Norman architecture in Britain, it has the largest Romanesque crossing tower in Europe. Tewkesbury had been a centre for worship since the 7th century. A priory was established there in the 10th century. The present building was started in the early 12th century. It was unsuccessfully used as a sanctuary in the Wars of the Roses. After the Dissolution of the Monasteries, Tewkesbury Abbey became the parish church for the town. George Gilbert Scott led the restoration of the building in the late 19th century. The church and churchyard within the abbey precincts include tombs and memorials to many of the aristocracy of the area. Services have been high church but now include Parish Eucharist, choral Mass, and Evensong. These services are accompanied by one of the church's three organs and choirs. There is a ring of twelve bells, hung for change ringing. History The Chronicle of Tewkesbury records that the first Christian worship was brought to the area by Theoc, a missionary from Northumbria, who built his cell in the mid-7th century near a gravel spit where the Severn and Avon rivers join. The cell was succeeded by a monastery in 715, but nothing remaining of it has been identified. In the 10th century the religious foundation at Tewkesbury became a priory subordinate to the Benedictine Cranborne Abbey in Dorset. In 1087, William the Conqueror gave the manor of Tewkesbury to his cousin, Robert Fitzhamon, who, with Giraldus, Abbot of Cranborne, founded the present abbey in 1092. Building of the present Abbey church did not start until 1102, employing Caen stone imported from Normandy and floated up the Severn. Robert Fitzhamon was wounded at Falaise in Normandy in 1105 and died two years later, but his son-in-law, Robert FitzRoy, the natural son of Henry I who was made Earl of Gloucester, continued to fund the building work. The Abbey's greatest single later patron was Lady Eleanor le Despenser, last of the De Clare heirs of FitzRoy. In the High Middle Ages, Tewkesbury became one of the richest abbeys of England. After the Battle of Tewkesbury in the Wars of the Roses on 4 May 1471, some of the defeated Lancastrians sought sanctuary
