Mishkova niva, Thracian ruins near Malko Tarnovo, Bulgaria

Mishkova Niva is a Thracian sanctuary centred on the Great Mound, where a monumental wall of three rows of white local marble blocks, 25 m in diameter and 1.80 m high, encloses a domed tomb with a covered dromos and a circular chamber. The entrance pediment was decorated with a shield, a spear and two open palms; a rectangular room of broken granite and a stone circle around granite slabs, remains of a destroyed dolmen, stand nearby.

The sanctuary began as a megalithic dolmen with an enclosure in the mid-2nd millennium BC, later becoming a heroon and temenos of Apollo Aulariokos as nearby iron mines were worked. A 2nd-century AD altar records Straton, son of Straton, leader of the Greeks in the iron mines, and the site was used until the 4th–6th centuries AD. Karel Škorpil published the first study in 1926.

The sanctuary's name is not recorded, but its inscriptions name Apollo Aulariokos, a local epithet of the god, and Zeus-Dionysos as the main deities of the Malko Tarnovo area. A marble altar found here bears a dedication by Straton, son of Straton, leader of the Greeks working the iron mines, from the eighteenth year of Antoninus's reign (2nd century AD). Votive tablets with the Thracian Horseman were also found.

The location lies several kilometers away in a rural area, so a car or local guide is important for visiting. It is best to visit during daylight to see the various structures and remains clearly.
