The numerous ceramic finds, tracing back to the Classical Age and kept in the National Museum of "Magna Grecia" in Taranto, reveal the antique roots of this handicrafts production which was privileged by the presence of considerable amounts of clay in the surrounding territory. More recently, records dating back to the 18th century report at the time 42 companies in Grottaglie operating in the ceramics-sector with a total of 5,000 employees. In addition to ceramics, also agricultural products such as olive oil and excellent choice dessert grapes are of great importance.
