The National History Museum displays this month the Unseen Thracian Gold Treasure from Plovdiv. It consists of 150 objects discovered in 2001 near the village of Kaloyanovo, just outside Plovdiv. The treasure belonged to a Thracian king who lived during the 5th century B.C. and includes the heaviest solid-gold Thracian breastplate ever found on the Balkan. The unique piece-weighting 250 grams of 24-carat gold-has an ornament portraying Medusa Gorgona, the Greek goddess of horror.
