Duddo Five Stones: Art by Bladup, lots more in our Art section #StandingStoneSunday. This circle in Northumberland lies atop a hill surrounded by farmland. One of the stones was re-erected in the 1920s and Burl believes that it is probable that they have all been re-erected at some point. Burl wrote that the direction the stones face in the circle is wrong and that some of them rock under little pressure.
