This is in Season 3 of Ozark that was just released. It’s set in Michoacán, Mexico although the filming is in Georgia, US. They briefly used Chicago in the first season.
I know the moderators will probably want this in Cafe Society however a very difficult location was found before that I posted, probably because it was allowed to be in General Questions. I think if this was moved to Cafe Society it might not be solved. It’s more about the building than the show.
I’m very surprised that I haven’t found it yet. It seems like a tourist attraction not a private residence like it is in the show.
I’ve searched Spanish mission, fort, chateau, and villa for Georgia in Google Images.
You may have done this already, but perhaps search states adjacent to Georgia? It could be close enough to the main filming site in Georgia to make it a reasonable distance to travel when they need to film exterior shots.
If this is keeping you up at night, you might want to contact the production companies and ask them. They may or may not know, but it’s worth a try. The two production companies listed in IMDB are Zero Gravity Management and Media Rights Capital (MRC). Good luck, and let us know if you ever solve this mystery.
Going about it in a different way, is there metadata attached to those images that might include gps info? I’d guess you may need an imgbb account to get the metadata, if it is available.
If the images are stills they could be from anywhere. What I see looks more Old World than New World to me. In the OPs second link, there are a couple of Moorish-looking windows below the belfry.
There’s a cross on the belfry, so I’d search for terms like monastery, seminary, etc. (not fort).
