Ok for being such a minor part of the books it’s impressive how much sense Dol Amroth makes.
It’s the richest region of Gondor, probably because it’s costal and has access to a harbor. So everyone works hard to keep the prince on their side. Princesses marry the sons of stewards, etc.
I frequently ask friends "if you were from Middle-earth, where would you be from and what race would you be?" and a friend who, as far as I knew, was not super into LOTR immediately and without hesitation named Dol Amroth. I was impressed.
