Salut Tom,

Presumably, the city today has a recognised boundary to it that is no longer as it was historically.

So reference to the former boundary city wall would be, just that, the former wall.

It is an interesting point that you raise but to express this as the former wall could work within my understanding of the context.

Hope this helps.

Bonne journée

Thanks Jim.

Come to that, it's both former and ancient, so it's still surprising that "mur ancien" (the literal translation) is marked wrong. 

This one has got me before; there does seem to be some rule about the position of "ancien" in complex descriptions, but I can't find it explained.

Bonjour Adrian,

I understand your frustration -- this is a very tricky aspect of French grammar.

I have included a couple of previous posts which I hope will give you a wider understanding of this issue as discussed in the past.

I hope that you will find this input helpful.

Bonne journée
