Swinside Stone Circle Swinside Stone Circle, which is also known as Sunkenkirk and Swineshead, is a stone circle lying beside Swinside Fell, part of Black Combe in southern Cumbria, North West England. It has been suggested that most archaeologists concur that the circles in this area were built for ritual or ceremonial reasons, the stone circles Castlerigg and Long Meg, and her Daughters are in this area. The circle is 27m in diameter with 47 stones on the circumference and 1 further stone at 19°, although there are a total of 55 stones originally, there could have been 60 stones. Coordinates 54.282497,-3.273838 Angles If the circle is split by a line that goes through each double stone , then angles 10,19, and 9 0° are produced with the 90° at maximum tilt. This then splits the circle in half with 20 stones in total towards the west and 27 towards the east. The 10 and 19 lines also split the circle, and the corresponding number of stones per segment are 9,1,10 west and 15,4,8 east.
