It's a Temple Artifact and can be held in all three Temples.
Again, I would disagree with their placement in the other temples. The only temple with any biblical evidence for Golden Cherubim was Solomon's Temple, and there are other historical sources that seem to indicate that at least the Z-Temple did not include them. This artifact is the very definition of a Solomon's Temple Artifact, and should not be a Temple Artifact based on the sources we have.
