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.
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.
