Hello, I was doing the writing exercise, Catherine Ségurane: a local heroine, I came across this sentence:
If you look behind me, on the ancient wall of the city,
I put ancien after mur but the correct answer is:
Si vous regardez derrière moi, sur l'ancien mur de la cité
And no, there was no hint about that. I really don't understand why we use ancien before the noun in that case.
