Place where ties knotted (4)
I believe the answer is:
site
'place' is the definition.
(I know that site is a type of place)
'ties knotted' is the wordplay.
'knotted' indicates anagramming the letters.
'ties' with letters rearranged gives 'SITE'.
'where' acts as a link.
(Other definitions for site that I've seen before include "Location (of building, dig etc)" , "Where something is located" , "Location; locate" , "Spot, location" , "Somewhere to build, perhaps" .)
