I believe the answer is:

turin

I'm a little stuck... Click here to teach me more about this clue!

'italian location' is the definition.
(I've seen this before)

I don't understand how the remainder of the clue works.

(Other definitions for turin that I've seen before include "It. city housing shroud" , "N. Italian industrial city" , "I turn to the Italian city" , "Italian location" , "Italian city with sacred Christian Shroud" .)

I've seen this clue in The Independent and The Sun.
