Cobweb site (5)
I believe the answer is:
attic
'cobweb site' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for attic that I've seen before include "Floor" , "where high-ups are found?" , "Area at the top of the house" , "Tacit (anag.)" , "Dusty room" .)
