Prospect of Cape Corse, or Coast Castle
This engraving shows the top plan of Cape Coast Castle and other features surrounding the castle, e.g., the town, various paths. The bottom plan depicts gun placements, warehouses, barracks, etc. Astley adapted this image from William Smith, who was a surveyor employed by the Royal African Company in 1726 to survey their forts in West Africa. Thomas Astley (d. 1759) was a British bookseller and publisher who never went to Africa. His imagined localities and illustrations of Africa were informed by a library of travel books at his disposal.
