Some edifice, not a pharaoh's tomb (8)

I believe the answer is:

cenotaph

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

'some edifice not a pharaoh's' is the wordplay.
'some' says the answer is hidden in the clue (some of the parts of the word are used).
'CENOTAPH' can be found hidden inside 'edifice not a pharaohs'.

(Other definitions for cenotaph that I've seen before include "War memorial" , "Whitehall monument" , "Whitehall memorial" , "Empty tomb" , "Feature of Whitehall" .)

I've seen this clue in The Telegraph.
