Penkridge
This plan covers part of Staffordshire, with Cannock Chase depicted at top right. Framed by the more formal landscapes of Haywood Park, Oakedge Park and Wolseley Park, this large area of heathland was once a great medieval hunting forest favoured by royalty. Triangles are clearly visible outside the plan, and trigonometrical calculations are noted in a table at bottom right.
