In the 12th century the town was founded and a castle erected on Knudshoved (Canute's Head) by Knud, nephew of Waldemar the Great; and from the 13th to the 15th century Nyborg was one of the most important places in Denmark.
Canute's ships were then at Greenwich on their way to London, where they soon afterwards arrived.
The concluding years of Canute's reign were peaceful, as became a prince who, though by no means a coward, was not of an overwhelmingly martial temperament.
The war continued intermittently till 1201, when Duke Valdemar, Canute's younger brother, conquered the whole of Holstein, and Duke Adolf was subsequently captured at Hamburg and sent in chains to Denmark.
St Canute's cathedral, formerly connected with the great Benedictine monastery of the same name, is one of the largest and finest buildings of its kind in Denmark.
St Canute's shrine was a great resort of pilgrims throughout the middle ages.
Of all European lands England is without doubt that on which the Viking Age has left most impression: in the number of original settlers after 878; in the way which these prepared for Canute's conquest; and finally in that which she absorbed from the conquering Normans.
His birth and origin are utterly uncertain; but he rose to power early in Canute's reign and was an earl in 1018.
