In Spain, which is suffering its worst drought in decades, archaeologists are thrilled to discover a prehistoric stone circle called the “Spanish Stonehenge” that was usually covered by dam water. Officially known as the Guadalperal Dolmen, the stone circle is now fully exposed in one corner of the man-made Lake Valdecanas, in the central province of Cáceres, where authorities say the water level has dropped to 28 percent of capacity.

Italy declared a state of emergency for the areas around the Po River, and at the end of July a sunken World War II bomb weighing 450 kilograms was discovered in the shallow waters of the country’s longest river.
