An underwater medieval village in Spain can be seen for the first time in years, because water levels have sunk so low. The ancient stone buildings and a church with a spire, were flooded in the 1960s, to make a reservoir near Barcelona. But the city has just had its driest period for the last 60 years, and is suffering from a severe water shortage. Usually, there would be lots of water in the reservoirs at this time of year, but for the last few years the winters have been dry. Water supplies are being shipped in giant tankers. People in the area are shocked, because it’s the first time things have got so bad.
