Prehistoric town unearthed

The remains of a small settlement made of two-story houses near the modern-day town of Provadia, in eastern Bulgaria. Archeologists say they have discovered the oldest prehistoric town ever found in Europe, which was built around an ancient salt production site and dates back to the fifth millennium BC. A team has been working since 2005 to excavate the site, which is near the Black Sea resort of Varna. Bulgarian National Institute of Archeology via Agence France-Presse
