It's hard to say Avignon when you read it in English. The "g" is ignored and there should be a "y" pronounced there and you don't say the last "n". But it's French and they love extra letters in their words and at the same time, love not to pronounce them. Many French words have a surfeit of sounds available to them that are not apparent when you look at them and then seem to waste, perfectly good syllables in a devil-may-care attitude toward finishing what they've started. Parts of the City of Avignon are like that. In fact there's the famous pont d'Avignon from the children's song that has only 3 wonderfully decorated arches that daintily step out into the middle of the river but do not reach the other side...sort of like the good start but breathy finish of a French word. Avignon.
