BBC Two's multi-award-winning Secret History of Our Streets told the story of six London streets, from Victorian times to the present day.
Now, as its people stand at a crossroads in their history, the series travels to Scotland to tell the stories of three archetypal streets in Scotland's three great cities: Edinburgh, Glasgow and Aberdeen.
Endlessly surprising and not at all what you would expect, the stories of these streets are the story of a nation.
At the mouth of Aberdeen Harbour lie the Fittie Squares, a model housing scheme built for fishermen and their families in 1809.
Tethered to the sea and cut off from the city, the squares developed their own culture. They were a traditional fishing community, untroubled for 150 years, until the day that oil was discovered just a few miles out to sea.
