Kardzhali province is situated in the southern part of the country, bordering Greece. It was named after the city of the same name, which got its name from the Ottoman leader - Kirca Ali.
The region was first inhabited in Neolithic times by the Thracians. The former residence of the Thracian king, Peperikon, is the largest megalithic construction in the Balkans.
Near the village of Nenkovo, an artificial cave was discovered. The cave is formed in the shape of a woman's womb. When the sun is highest in the sky, at noon, a ray of light forms a phallic shaped shadow in the cave. Thracians believed this was where the sun god was conceived.
The Stone Wedding is a stone formation resembling a group of people near the village of Zimzelen. Legend says that a future father-in-law saw the beauty of the bride-to-be, and wished her for himself. The wind became angry and turned the whole wedding into stones. The stone formations are around 40 million years old.
The economy of the Kardzhali region is mostly retail-dependant, although the region's large lead and zinc deposits has a great potential for metallurgy.
