Royal residence listed crown as lost (7,6)
I believe the answer is:
windsor castle
'royal residence' is the definition.
(I've seen this before)
'listed crown as lost' is the wordplay.
'lost' indicates an anagram.
'listed'+'crown'+'as'='listedcrownas'
'listedcrownas' with letters rearranged gives 'WINDSOR CASTLE'.
(Other definitions for windsor castle that I've seen before include "Royal residence" , "Queen's residence" , "palace" , "royal house" .)
