I am stuck with question 2 in the Sunday Times Where Was I , the clues I have solved lead to the number 16, which is "architecturally significant at a house where the trail ends, 10 miles away". I have been following a route (not a specific trail?) and am currently at the Marker's Cottage , Killerton, Devon. The question is: At which building did the trail end?
Any clues would be appreciated.
