Are a Civ's Unique Buildings transformed when conquered? [duplicate]

Assume for a moment that I am playing the Ethiopians, currently at war with the Egyptian empire.

Egypt has a unique building, the Burial Tomb, that replaces the Temple. My spies have already told me that the Egyptian city of "InvadeMe" contains one of these, as well as a generic Monument building.

If my forces conquer the city, what happens?

• Does the Burial Tomb get converted into a Temple? (Since Ethiopians can only build Temples)
• Does the Monument get converted into a Stele? (Since Ethiopians can't build generic monuments)

(I just used Ethiopians off the top of my head, this question is not G&K specific)

Solution 1:

Short answer: They convert to the correct building of the conquering Civilization, if they survive at all.

I fired up Civ V, with the In-Game Editor mod running. It doesn't edit any mechanics, so it's great for testing out things like this. No other mods were running.

I played as Assyria, against Egypt. I would have involved Ethiopia, as per your example, but my experience suggests that cultural buildings never survive, so Steles/Monuments wouldn't work either way. I gave Egypt a second City, with the techs needed, and added a Library, Shrine, and Burial Tomb.

Then, I declared war, gave myself a Giant Death Robot in the area, and took the city. Once under my control, Memphis had a Royal Library and Temple instead.
