Refuges, sanctuaries (7)
I believe the answer is:
asylums
I believe this clue is a double definition.
'refuges' is the first definition.
('asylum' can be a synonym of 'refuge')
'sanctuaries' is the second definition.
('asylum' can be a synonym of 'sanctuary')
(Other definitions for asylums that I've seen before include "Places of refuge" , "Sanctuaries or psychiatric institutions" , "'Refuges, sanctuaries (7)'" , "Nuts were kept here" , "They shelter" .)
