College founded by Henry VI (4)
I believe the answer is:
eton
'college founded by henry vi' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eton that I've seen before include "Posh British public school" , "College in Berkshire" , "Place for learning" , "Famous English public school" , "Berkshire public school" .)
