Starosel

The village of Starosel – about 20 km away from Hisarya. Here in 2000 was found exceptional Thracian sanctuary dating from 5th – 4th century B.C. The village was in Antiquity an important and wealthy Thracian city in the 5th century BC, as evidenced by the excavations in the 20th century. The largest underground temple in the Balkans is found under the Chetinyova Mogila (tumulus), along with a mausoleum. The temple as well as nearby Thracian king's residence under Mount Kozi Gramadi were likely built during the reign of Amatokos II (359-351 BC). Other sites include the Horizont tumulus, where the only known Thracian temple featuring a colonnade (a Doric one) is located, as well as 9 other tumuli in the surrounding area.

Through a peristyle a visitor can reach an inner hall. Various objects found here could be seen today in the Archaeological museum and in the National Historical museum.
