Mategriffon

Mategriffon or Mategrifon or Mathegriffon was a medieval castle near Messina, Sicily, initially built as a wooden castle by Richard Ist, king of England and demolished before his departure in 1191 from Messina for the conquest of Cyprus. Another reference to the castle is also made during the Sicilian Vespers, as the place where Charles I of Naples's Vicar Herbert and his family safely stayed during the uprising until their safe departure was negotiated.

Mattegriffon was also an alternative name to the castle of Akova in the Peloponnese, which formed the seat of the Barony of Akova within the Principality of Achaea in the 13th and the 14th centuries.
