The drying up of rivers in Europe and Asia reveals secrets and treasures that were hidden under the water

Arab weather - an exceptional weather that imposed itself this year on many countries of the world, where climate changes continue to amaze us with their effects, until some countries in Europe and Asia witnessed one of the worst droughts in history.

As more important rivers and lakes dried up, secrets and treasures that had been hidden under water for tens and even thousands of years were revealed.

Dolmen Guadalberal stone in Spain

In Spain, which is experiencing its worst drought in decades, archaeologists have been delighted with the appearance of a prehistoric stone circle called the "Spanish Stonehenge" that is usually covered by the waters of a dam.

Officially known as the Dolmen of Guadalperal, the stone circle is now completely bare in one corner of the Valdecanas Reservoir, in the central province of Cáceres, where authorities say the water level has fallen to 28% of its capacity.

Hunger stones in the Czech Republic and Germany

Memories of past droughts in Germany were also renewed by the re-emergence of the so-called "stones of hunger" along the Rhine. Many of these stones have become visible along the banks of Germany's largest river in recent weeks.

The reappearance of the stones is seen as a warning and reminder of the hardships people faced during previous droughts. The dates visible on the stones seen in Worms, south of Frankfurt, and Rheindorf, near Leverkusen, included the years 1947, 1959, 2003 and 2018.

Remnants of World War II in the Danube River

With Europe's worst drought in years, the mighty Danube River has reached one of its lowest levels in nearly a century, exposing the hulls of dozens of German warships laden with explosives that sank during World War II near the Serbian port city of Brahovo.

The ships were among the hundreds sunk by Nazi Germany's Black Sea Fleet along the Danube in 1944 as they withdrew from advancing Soviet forces, and they continue to impede river traffic as water levels drop.

This year's drought exposed more than 20 structures along the Danube near Brahovo in eastern Serbia, many of which still contain tons of ammunition and explosives and pose a shipping hazard.

“The German fleet has left behind a major environmental catastrophe that threatens us residents of Prahovo,” said Velimir Trajelovic, 74, a retiree from Prahovo, who has written a book about German ships. On the other side of the river.

A bomb on the bank of the Po River in Italy

Italy declared a state of emergency in the areas around the Po River in late July when it discovered a 450 kg (1,000 lb) bomb from the Second World War after the country's longest river fell.

About 3,000 people living near the northern village of Borgo Virgilio near Mantua were evacuated, while military experts neutralized and carried out a controlled detonation of the US-made device earlier this month.

Statues in the Yangtze River, China

The rapid decline in the water level of the Yangtze River in China has revealed a submerged island in the southwestern city of Chongqing and three Buddhist statues believed to be 600 years old.

Water levels in the Yangtze River dropped rapidly due to drought and heat wave in southwestern China, where rainfall in the Yangtze Basin has been about 45 percent less than normal since July, and as many as 66 rivers have dried up in 34 provinces in Chongqing, according to the report. China's CCTV reported on Friday (August 19).
