Sanctuary, asylum (6)
I believe the answer is:
refuge
I believe this clue is a double definition.
'sanctuary' is the first definition.
(I know that sanctuary can be written as refuge)
'asylum' is the second definition.
(I know that asylum can be written as refuge)
(Other definitions for refuge that I've seen before include "Place of safety" , "Shelter or protection from danger or trouble" , "Place of retreat, sanctuary" , "The sort of shelter" , "Traffic island" .)
