I also think associating the Winterers with winter is, while an understandable mistake to make, undoubtedly a mistake. Nothing of the little we've heard about the Withering from Halmarut suggests it's in any way related to cold weather (and in fact has never been called a 'great winter'), and in fact given 'winterers' as a term are for things like hummingbirds that specifically aren't around for cold weather, we should just assume no coldness is related to the Winterers in turn.
With something like this, I suggest thinking of the most low-key possible answer: that rather than jumping to the most grandiose possible theories, you instead consider something that most readily answers all of our questions, in a way that's as small as possible, with the logic that the real answer will be somewhere between the two--and, given all context, probably closer to the lower end, because they're not gonna stake their game-changing reveal on a dungeon that looks like a boring part of New York in December.
In this case, the smallest possible answer I can think of is that it's just another part of the city of Garlemald; far enough away from the military and political center we visited that it didn't get hit by the same treatment, but still basically got abandoned. You walk around whatever your nearest big city is, and you'll definitely see architectural differences between the commercial areas and wherever government house is; this could just be that. Alternatively, it's a neighboring city that's just far enough out to have a slightly different arcitectural style; maybe Landis.
