Dwellings and a church dating from the 11th century, normally located at the bottom of the Sau reservoir in Catalonia, are now visible due to the lack of water. The Sau reservoir is one of the nine reservoirs in Catalonia.
It is the second largest in terms of capacity and usually supplies water to 6 million people. Never has such a low level been observed since its creation 60 years ago. The city of Barcelona and its outskirts have been placed in a drought “state of emergency” since February 1.
