Reconstruction of the

1. Draw a circle. This forms the outer border of the ring in the formation.

2. Draw 7 rays regularly spaced around the circle.

3. Draw one set of diagonals (with the smallest enclosed circle).

4. Draw this enclosed circle. It forms the inner circle of the formation.

5. Construct a small heptagon (regular 7-sided polygon) from the intersections of this circle and the rays.

6. Extend the sides of this heptagon until they meet (at the rays). A sharp 7-pointed star appears.

7. Draw a circle through the points of this star. This forms the inner border of the ring.

8. The extended sides form also a smaller 7-pointed star. From the star-points, construct again a heptagon.

9. Extend the sides of this heptagon also, until they meet at the rays.

10. Draw a circle through the star-points. This forms the middle circle of the formation.

11. Construct a circle through the given points, that is, through the intersections of two rays, three apart, and the inner ring border, and touching the middle circle at the opposite side.

12. Repeat this 6 times, 7 in total.

13. From all these circles, trim away everything except the part in between two rays, two apart, as shown. (All in the same sense). These form the outer borders of the "horns" in the formation.

14. In the sharp pointed star from step 6, construct the inscribed (small) circle.

15. Similar to the one in step 11, construct a circle through the given points: through the intersections of two rays, three apart, and the inner ring border, this time touching at the far side the small circle just constructed.

16. Repeat this again 6 times (7 in total).

17. And again, from all these circles, trim away everything except the part in between the arrows, that means, from one ray to the larger of the two inner small circles, as shown. (All in the same sense as in step 13). These form the inner borders of the horns.

18. Construct a circle through the intersections of the middle circle with two inner horn borders, two apart, and touching the smallest circle at the near side, as shown.

19. Repeat this 6 times, 7 in total.

20. From these circles, trim away everything but the parts in between two adjacent inner horn borders, as shown.

21. This concludes the reconstruction of the first version of the formation.

The result matched with the aerial image. At some places it does not fit exactly.

23. Later on, the Circlemakers "finished" the formation.

To continue the reconstruction, construct a circle through two adjacent horn endpoints, and touching a third horn at the outer border, as shown.

24. Repeat this up to a total of 7.

25. Trim away all parts of the circles that fall outside the horn endpoints and the adjacent outer horn borders, as shown.

26. This finishes the reconstruction of the 2000 Broadbury Banks (2) formation.
