Tall structure producing lofty tolls (4,5)

I believe the answer is:

bell tower

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

'tall structure' is the definition.
'bell tower' can be an answer for 'structure' (bell tower is a kind of structure). I am not certain of the 'tall' bit.

I cannot understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for bell tower that I've seen before include "Campanile" , "building to encourage worshippers to come along?" .)

I've seen this clue in The Telegraph.
