It helps us if you can provide FULL question details please, including letter counts and any letters that you've already got filled in.
Further, if you're doing a crossword or quiz where the answers tend to refer to a particular part of the UK, it helps us to know that. For example, I see from your previous posts that you might be doing Keith's crossword, where the answers often refer to Scotland. If so, these might be possible answers for your clue:
Calanais
Machrie Moor
Ring of Brodgar
The Twelve Apostles
Stenness
Kilmartin Glen
