Dig explores history of ancient Greek dikes

Archaeologists excavating a vast 3,300-year-old fortress north-west of Athens are hoping to shed light on one of the most impressive engineering feats of ancient Greece.

The ministry of culture says the results of work at Glas have been “encouraging”. For much of its history the area has been a lake and swamp, which was only drained in 1931. But, for a brief period in the 13th century BC, local rulers built huge dikes to create thousands of acres of farmland.
