King in utopia recalled unforgiving mountainous country (4,8)

I believe the answer is:
lake district
'king in utopia' is the definition.
The definition suggests a singular noun which matches the answer.
'recalled unforgiving mountainous country' is the wordplay.
I cannot really understand how this works, but
'unforgiving' could be 'strict' (I've seen this in another clue) and 'strict' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lake district that I've seen before include "in NW England" , "Area of mountains and meres" , "Cumbrian region" , "holiday location" , "Area associated with Wordsworth, Coleridge" .)
