I love Edinburgh, the blackened houses, the classical street plan, the New Town, the fact that there is so little new development, the back streets behind the façades and the views out towards the Kingdom of Fife.   Walking across the city from end to end in the early night, not a car, let alone a taxi, in sight, I was struck by how extraordinarily coherent it is, not a wrong note, as I went from Broughton Street in the east, through streets named in honour of Nelson’s victories, as each generation added street after street according to a consistent vocabulary, right through to the 1840s, and all miraculously preserved by a conservative Edinburgh establishment who have not allowed high rise:-
