Column of soldiers in Mount Tumbledown? (8)
I believe the answer is:
monument
'column' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for monument that I've seen before include "Memorial structure" , "London tube station" , "cairn" , "Commemorative structure" , "Could be column" .)
