Laval University

Laval University in Quebec City flies a banner of arms. I am not sure whether the flag is 1:2 or 2:3. The arms inverse the color-metal pairs of those of Monseigneur François de Montmorency-Laval, first bishop of New France, who founded the Quebec Seminary in 1663, from which Laval University was to stem in 1852.

On the family arms, the alerions were originally 4 in number, but after Mathieu II de Montmorency took Emma de Laval as his wife around 1218 A.D., they multiplied to 16. Five scallops were added onto the cross in 1250 when Guy VII de Montmorency inherited the lands of his half brother, Mathieu d'Attichy.

Interestingly, the city of Laval (a suburb of Montreal) also uses a variation on the family arms of François de Laval by inversing the metals (Ed: arms not shown on FOTW):

 

Laval	Family	University	City
shield:	Or	Gules	Argent
cross:	Gules	Or	Gules
alerions:	Azure	Argent	Azure
scallops:	Argent	Azure	Or

Note that the Commune de Laval in France uses the original family arms, which were gules, a leopard or.
