Ruined ancestral city (9)

I believe the answer is:

lancaster

'city' is the definition.
(Lancaster is an example)

'ruined ancestral' is the wordplay.
'ruined' indicates anagramming the letters.
'ancestral' with letters rearranged gives 'LANCASTER'.

(Other definitions for lancaster that I've seen before include "A rose-red city" , "City of NW England" , "WW2 aircraft; city" , "it bombed" , "WW2 bomber; city" .)

I've seen this clue in The Telegraph.
