Maps have many parts. Here is a map of the Bohemian Kingdom (part of the present Czech Republic) from the middle of the 18th century. Drag your mouse across the map to find eight “hidden” map components. Be sure to look in the map’s center and around its edges. When you locate one of the “hidden” elements, it will change color. Click on it and answer the question that appears in a new window. Click here for an enlarged view of the map.
