Beautifully furnished place enclosed by remarkably deep wall (4-9)
I believe the answer is:
well-appointed
'beautifully furnished' is the definition.
'well-appointed' can be an answer for 'furnished' (similar in meaning). I'm not sure about the 'beautifully' bit.
'place enclosed by remarkably deep wall' is the wordplay.
I cannot really see how this works, but
'place' could be 'point' and 'point' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for well-appointed that I've seen before include "(Of room/building) finely fitted-out" , "Properly supplied" , "Fully equipped" .)
