Collection is raised in places (5)
I believe the answer is:
sites
'places' is the definition.
(a site is a place or location)
'collection is raised' is the wordplay.
'collection' becomes 'set' (set is a kind of collection).
'raised' says the letters should be written in reverse (going up in a down clue).
'set'+'is'='setis'
'setis' in reverse letter order is 'SITES'.
'in' acts as a link.
(Other definitions for sites that I've seen before include "Locates" , "Is set (anag)" , "Spots" , "Is set among building locations" , "places" .)
