Thank you.
And as you say, the Glottkin map has it to the SW of the Temple. I think it is safe to say, however, that there is only one Imperial Zoo/Menagerie. I have noticed several other discrepancies (regarding names and locations) between the Glottkin map and earlier maps (like Seter's). Of course, those maps may not be "official" as such, but did try to incorporate all the available information from various official sources, which often are unclear or even contradictory. Glottkin is official, but it is also known that GW often chooses to simply ignore earlier fluff.
