Kara Yin Thracian tomb XI – VIII century BC.
The Kara Yin tomb was discovered by Haskovo local historian Boris Kolev, who discovered several more rock tombs in the area. It was studied by archaeologist Georgi Nehrizov. The rock massif in which it is carved is known as Ak Kaya (from the Turkish White Rock) because of its light color. The rocks are of volcanic origin, and their shapes are strange and strange, due to weathering over time. In general, rock-cut tombs precede dolmens. Most researchers associate them with the Thracians. Their dating is in the period XI – VIII century BC.
