The Structure of Greek Noun Phrases

I continue to struggle with the relationship between postnominal modifiers and their head noun.

When we have the ordering: D(eterminer) N(oun) D A(djective), what exactly is going on? Is it:

[DN[DA]] [τὴν πόλιν [τὴν μεγάλην]]

where the modifying DA phrase is a sister to the Noun?

Or is the structure:

[DN][DA] [τὴν πόλιν] [τὴν μεγάλην]

where the modifying DA phrase is a sister to the DN phrase.

Does the repeated article suggest the second structure more than the first? Or are both structures possible depending on semantic and/or pragmatic factors?

Any ideas anyone?
