(Curator Note: The Canton of Fauquembergues is a former canton situated in the Nord-Pas-de-Calais region of France. It was disbanded following the French canton reorganisation which came into effect in March 2015. It consisted of 18 communes, which joined the canton of Fruges in 2015. First mentioned in 961 as "in monten qui dicitur Falcoberg", the place later in 1124 was called Falkenberga, also Valkenburg, and used the same coat of arms as Saint-Omer. The 13th-century church of Saint-Léger is a registered historical monument.)
