Under King Alfred, Winchester became the most important town in Wessex. He invested in its defences, and had the city rebuilt within the walls. At his death he was buried in the Cathedral (Old Minster). Either he or his son Edward began the building of the New Minster, an abbey, immediately adjacent to the Old Minster. The same area, south of the High Street, also housed the royal place and the Nunnaminster, a house of nuns founded by Edward’s mother, the Mercian Ealswith. Winchester was extensively excavated in the 1960s, and the excavation report is currently (2011) being prepared for publication.
