The exhibition Yatvings. The forgotten warriors tells the story of this most powerful of Old Prussian tribes reconstructed from archaeological evidence and the latest findings made by historians. During the early Middle Ages the pagan Yatving horsemen-warriors spread terror in their region and have been described in chronicles and other documents of the age as ruthless raiders. After their defeat, the Yatving territory became depopulated and was carved up by its neighbours; the memory of this bold Balt nation was gradually lost. The most recent archeological discoveries made at Szurpiły in Jeleniewo commune, at Skomack Wielki (Ostrów) in Stare Juchy Commune, and in other major centres of early medieval Yatvingia in Poland  confirm the military character of Yatving culture and help to bring back this intriguing people from obscurity.

The exhibition comprises 11 display panels and 6 display cases containing 141 archaeological objects, mostly weapons and other items of military equipment as well as Yatving personal ornaments now held by several museums in Poland (Museum of Warmia and Mazury in Olsztyn, District Museum in Suwałki, State Archaeological Museum in Warsaw).

The exhibition opened at Jeleniewo on 18 September 2015; on the same occasion Łucja and Jerzy Okulicz-Kozaryn, two eminent Polish prehistorians with interest in Balt archaeology were remembered as well: their name was given to the Yatving Centre at Szurpiły. The exhibition was next taken to Ełk (15 October-15 November 2015) and to the State Archaeological Museum in Warsaw where it is scheduled to run until the end of February 2016. Later still it will be shown in Norway at Borre and Kristiansand
