The Old Minster was the Anglo-Saxon cathedral for the diocese of Wessex and then Winchester from 660 to 1093. It stood on a site immediately north of and partially beneath its successor, Winchester Cathedral. The Old Minster was excavated in the 1960s. The outline of the building now is laid out in brickwork in the churchyard adjoining Winchester Cathedral. Saint Swithun's first grave is clearly marked. Finds from the site may be seen in the Winchester City Museum. The bones of the monarchs removed to the cathedral are now housed in the famous mortuary chests around the choir.
