Archaeologists in eastern Bulgaria say they have unearthed the oldest prehistoric town ever found in Europe, along with an ancient salt production site that gives a strong clue about why massive riches were discovered in the region.
This handout photo, provided by the Bulgarian National Institute of Archeology, shows the remains of a small settlement made of two-story houses near the town of Provadia in eastern Bulgaria. Archeologists have uncovered the remains of what could be the oldest prehistoric city in Europe founded around a salt mine and dating back to the fith millennium BC.
Excavations at the site near the modern-day town of Provadia have so far uncovered the remains of a settlement of two-storey houses, a series of pits used for rituals as well as parts of a gate, bastion structures and three later fortification walls -- all carbon dated between the middle and late Chalcolithic age from 4,700 to 4,200 BC.
