Note chap going around memorial (8)
I believe the answer is:
cenotaph
'memorial' is the definition.
(cenotaph is a kind of memorial)
'note chap going around' is the wordplay.
'going around' is an anagram indicator.
'note'+'chap'='notechap'
'notechap' with letters rearranged gives 'CENOTAPH'.
(Other definitions for cenotaph that I've seen before include "Monument honouring persons buried elsewhere" , "Whitehall monument" , "Monument to those killed in war" , "construction in Whitehall" , "Whitehall memorial" .)
