Translation:Halle is also a city in Germany.
I don't think it ever goes explicitly to the end.
Adverbs usually go after the verb.
If there is nothing else after the verb, then auch might coincidentally be at the end of the sentence, e.g. Ich singe auch. "I sing, too."
But not because it was explicitly put "at the end of the sentence"; it's just that nothing else came after its position "after the verb".
