halacha - Walled cities for Purim other than Jerusalem

The holiday of Purim is unique in that some locations celebrate it on different days. The rule is: if the city was walled at the time of Joshua's conquest of the Land of Israel then they celebrate on the 15th of Adar, while everyone else celebrates on the 14th of Adar.

Are there any cities nowadays that celebrate Purim only on the 15th of Adar aside from Jerusalem?

[Things to consider include (but are not limited to) the lists of cities from the book of Joshua (eg Chapter 12), and the city Shushan itself. Do we know where these are? Do any Jews live there?]

EDIT: To clarify, I am looking for cities that celebrate (as I said above) only on the 15th like Jerusalem does, not cities that have some doubt and celebrate both days.
