Construction workers labouring in an industrial zone in the Dalmatian resort of Zadar have hit upon the remains of a Roman aqueduct stretching for 40 kilometres.
Archaeologists called to the scene think that it dates back to the time of Emperor Trajan, who came to this part of the coast in the early 2nd century to do battle with the Dacians.
The piping, 60cm in diameter, fed Zadar from the Biba spring near Vrana Lake, dropping around 25 metres as it did so. The historic centre of the city is dotted with wells, lending their names to prominent squares. Experts reckon that the supply from Lake Vrana came to Trg pet bunara, or Five Wells Square, a major landmark in town.
