Walter of Rosières

Walter of Rosières (French: Gauthier de Rosières) was a French knight who participated in the Fourth Crusade and became the first lord of the Barony of Akova in the Frankish Principality of Achaea. The Chronicle of Morea credits Walter with the construction of the fortress of Akova or Mattegrifon. He died childless, ca. 1273.
