Christianity was reintroduced to the Midlands at Repton, where some of the Mercian royal family under Peada were baptised in AD 653. Soon a double abbey under an abbess was built. In 669 the Bishop of Mercia translated his see from Repton to Lichfield. Offa, King of Mercia, seemed to resent his own bishops paying allegiance to the Archbishop of Canterbury in Kent who, while under Offa's control, was not of his own kingdom of Mercia. Offa therefore created his own Archdiocese of Lichfield, which presided over all the bishops from the Humber to the Thames. Repton was thus the forebear of the archdiocese of Lichfield, a third archdiocese of the English church: Lichfield, the other two being Canterbury and York. This lasted for only 16 years, however, before Mercia returned to being under the Archbishopric of Canterbury. At the centre of the village is the Church of England parish church dedicated to Saint Wystan who was a prince of Mercia, murdered by his guardian in 849, in the reign of Wiglaf. In 873–74 the DanishGreat Heathen Army overwintered at Repton, one of only a few places in England where a Viking winter camp has been located. Excavations from 1974 to 1988 found a D-shaped earthwork on a bluff, overlooking an arm of the River Trent, and opened a mound containing a mass grave. The mass grave contained the remains of at least 264 individuals. The bones were disarticulated and mostly jumbled together. Forensic study revealed that the individuals ranged in age from their late teens to about forty, four men to every woman. Five associated pennies fit well with the overwintering date of 873–74. The absence of injury marks suggest that the party had perhaps died from some kind of contagious disease. An early 18th century account describes how, in the last quarter of the 17th century, Thomas Walker, a workman looking for stone, opened the mound and found the skeleton of a "nine foot tall" man in a stone coffin in the remains of a building. According to the account, human bones had been neatly stacked around the coffin. It seems likely that Walker just threw most of the bones back once he had removed the stone he was seeking, but he was recorded as having kept the skull of the principal burial.
Parish church
The church is notable for its Anglo-Saxon crypt, which was built in the 8th century AD as a mausoleum for the Mercian royal family. Wystan, or Wigstan, was a prince of Mercia who was murdered by his guardian in 849, in the reign of Wiglaf. His remains were buried in the crypt at Repton and miracles were ascribed to them. Repton proceeded to become a place of pilgrimage; Wigstan was later canonised and became the patron saint of the church. At the north edge of the village is St Wystan's Church, an Anglo-Saxon church dedicated to the Anglo-Saxon Saint Wystan and designated by English Heritage as a Grade I listed building. The 8th-century crypt beneath the church was the original burial place of Saint Wigstan, as well as his grandfather, King Wiglaf of Mercia. Also buried there is King Æthelbald of Mercia, under whose reign the building was first constructed, and for whom it was first converted to a mausoleum. Upon the burial of St Wigstan, the crypt became a shrine and place of pilgrimage. The cruciform Anglo-Saxon church itself has had several additions and restorations throughout its history. These include Medieval Gothicnorth and southaisles in the nave that were rebuilt in the 13th century and widened early in the 14th century, and the addition in 1340 of the west tower and recessed spire. The church was also restored between 1885 and 1886 by Arthur Blomfield.
