Note 198 — PLATE LXXXIX. AND XC. CASTLE OF FALAISE.
Reading edition
At the same time that no record whatever has been preserved relative to the date of the building of the castle at Falaise, the Norman chroniclers have carefully recorded the æras of the erection of the other castles in the neighborhood. That of Domfront, according to them, was built a.d. 1011 and 1014, by the Counts of Alençon; that of Caen, by William the Conqueror, but much increased by his son, Henry I.; that of Vignats, a league and a half from Falaise, about the year 1096, during the dukedom of Robert, by Robert of Montgomery, Count of Alençon, and Viscount of Hiêmes and of Falaise; and that of Argentan, by Henry I. King of England, by way of protection against his son-in-law, Geoffrey Plantagenet.—Recherches Historiques sur Falaise, p. 22.
