Here lies Rovaniemi, a place bathed in light (7)
I believe the answer is:
lapland
'here lies rovaniemi' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'a place bathed in light' is the wordplay.
'place' becomes 'pl' (abbreviation used in postal addresses).
'bathed in' means one lot of letters goes inside another (I've seen this in other clues).
'light' becomes 'land' (light can mean to settle or land).
'a'+'pl'='apl'
'apl' going inside 'land' is 'LAPLAND'.
Can you help me to learn more?
(Other definitions for lapland that I've seen before include "Region of N. Europe" , "North Scandinavian region associated with Santa Claus" , "Finnish province" , "Father Christmas's home?" , "part of Europe" .)
