Prominent structure we located in rocky height
I believe the answer is:
tower
'prominent structure' is the definition.
'tower' can be an answer for 'structure' (tower is a kind of structure). I am not sure about the 'prominent' bit.
'we located in rocky height' is the wordplay.
'located in' indicates putting letters inside.
'rocky height' becomes 'tor' (I've seen this in another clue).
'we' put within 'tor' is 'TOWER'.
Can you help me to learn more?
(Other definitions for tower that I've seen before include "tugboat" , "Stand tall" , "Minaret, for example" , "Steeple" , "Tall column" .)
