Place: it’s within borders of Shropshire (4)
I believe the answer is:
site
'place' is the definition.
(I know that site is a type of place)
'it's within borders of shropshire' is the wordplay.
'within' is an insertion indicator.
'borders of' says to hollow out the word (remove centre letters).
'shropshire' with its centre taken out is 'se'.
'it' put inside 'se' is 'SITE'.
(Other definitions for site that I've seen before include "station" , "Web location; place" , "Building land" , "Locate, position" , "Location or piece of land" .)
