"When Stigand came from Selsey to establish his see in
Chichester he found the city already furnished with a minster
dedicated to St. Peter. He had effected this transfer because
the Council of London had decided in 1075 that the then
village sees should be removed to towns; and as there is no
evidence of any attempt to provide a new cathedral until
about the year 1088, the existing minster must have been
appropriated for the see."
