Area of land sacred to some (4)

I believe the answer is:

acre

'area of land' is the definition.
(I've seen this before)

'sacred to some' is the wordplay.
'to some' indicates a hidden word.
'ACRE' is hidden in the letters of 'sacred'.

(Other definitions for acre that I've seen before include "Mediterranean port" , "Imperial land measurement" , "4840 sq yds" , "Four roods - Israeli port" , "A state of W Brazil" .)

I've seen this clue in the Sydney Morning Herald.
