Tornow group
Tornow group, also known as Tornow-Klenica and Tornow-Gostyn in Poland, in archaeology refers to the Middle Slavic pottery and related strongholds of "Tornow-type" which were present in the middle of Obra, Oder, Spree but also Elbe and Saale basins from Greater Poland up to Thuringia. It is a derivation of Prague-Korchak (and possibly Sukow-Dziedzice culture in Northeastern part), and dated since late 8th or early 9th century up to late 10th or early 11th century.
