William the Conqueror

ALTHOUGH Rouen is now very far before all the other cities of Normandy in point of magnitude and importance, and though Rollo, in his conquest of the country, made it his principal headquarters and his main stronghold, it did not continue exclusively the residence of the dukes of Normandy in after years.
The father of William the Conqueror was Robert, who be-came subsequently the duke, the sixth in the line. He resided, at the time when William was born, in a great castle at Falaise. Falaise, as will be seen upon the map, is west of Rouen, and it stands, like Rouen, at some distance from the sea. The castle was built upon a hill, at a little distance from the town. It has long since ceased to be habitable, but the ruins still remain, giving a picturesque but mournful beauty to the eminence which they crown. They are often visited by travelers, who go to see the place where the great hero and conqueror was born.
It was about 870 that Rollo was banished from Norway, and a few years after that, at most, that he landed in France. It was not, however, until 912 that he concluded his treaty of peace with Charles, so as to be fully invested with the title of Duke of Normandy.
