The Penkovka culture (so called in its Ukrainian part) or Ipotesti-Candesti culture (in Romania) is an archaeological culture Ukraine spanning Moldova and reaching into Romania. Its western boundary is usually taken to at the middle Prut and Dniester rivers, where contact with the Korchak culture occurs.
Its bearers are commonly identified as the Antes people of 6th-century Byzantine historiography.
The core of the culture seems to be in Left-bank Ukraine, especially along the Sula, Seim, Psel, Donets and Oril rivers, but its territory extends to Right-bank Ukraine, and Penkovka pottery is also found in eastern and southern Romania, where it co-exists with wheel-made pottery of late Roman derivation; and is referred to as the Ipotesti-Candesti culture by Romanian archaeologists. Penkovka-type pottery has even been found in Byzantine forts in the north-eastern Balkans. "Nomadic" style wheel-made pottery (called Pastyrske or Saltovo ware) also occurs in the Ukrainian Penkovka sites as well as in the lower Danube and Bulgaria, but is most commonly found within the Saltovo-Mayaki culture, associated with Bulgars, Khazars and Alans.
Hand-made Penkovka pottery is distinguished from Prague-Korchak types on the basis of its biconical profile and tendency for out-turned rims. However, Florin Curta has argued that there can be no simple relationship between type of ceramic vessel and the ethnicity of groups which consumed them. E. Teodor performed a detailed analysis of ceramic vessels in 6th century southeastern Europe, and discovered a complex picture which cannot be reduced to 2 or 3 broad 'archaeological cultures', as each microregion and even individual site shows idisyncrasies in their ceramic profile and degree of connectivity to other regions of 'Slavic Europe'.
Penkovka settlements tended to be located on the terraces of rivers- usually arranged in a linear fashion. Buildings were usually square-shaped, post-hole constructs dug into the ground, and were equipped with an oven in the corners. There are also rounded buildings, otherwise not found in other Slavic territories, which have been associated with a nomadic influence. However, they are different from traditional tent-like nomadic yurts. Settlements tended to be abandoned after a period of habitation, and were often re-occupied years later, reflective of the itinerant form of agriculture practiced by the populace. Two fortified sites are known from the Penkovka region - Seliste and Pastyrske. The latter has been excavated in detail, and appears to have been an Iron Age fortification which was also occupied in early Medieval times. Measuring 25 ha, it included numerous settlement buildings as well as evidence of specialised industrial activity. Szmoniewski argues that "Pastyrs’ke may have also been a political power centre, the seat of a ruler with territorial authority".
