What is this medieval city-building game?

Screenshots and videos of this game have been bootlegged in many ads for various different cheap mobile phone games (that have nothing to do with the game shown in the pictures), and the game shown in the pictures is obviously for PCs or Macs since it uses a mouse. The PC game shown in the pictures actually looks rather fun, kind of like a better looking version of Banished...
Does anyone know what the name of it is?

I think this question has been answered exhaustively throughout the comments: it is footage of fake gameplay of a non-existing game, used as ads to lure in people to play run-of-the-mill casual games.

Reasoning:

• No additional or duplicate images can be found through reverse image search, none through regular searching;
• the UI seems inconsistent;
• there is a discrepancy between the linear perspective of the first images, and the isometric projection of the last (a feature which, is non-existent, AFAIK, or, at least, rare);
• in the first screenshot, the pathfinding (I assume that's what it is) seems to be wrong, leading me to believe it was cursorily added in post-production (or the pathfinding algorithm is just not optimal).

Also, as suggested in the other answer, it is quite obviously not Forge of Empires, because the two look completely different (even when considering the footage would come from pre-rendered trailers). As far as I could find similar games, it mostly resembles Foundation, but the architectural style and world scale are the most prominent differences.
