LTVilūnų neįtvirtinta gyvenvietė II (Kaišiadorių r., Kruonio sen.) lokalizuota 2020 m. balandžio mėnesį LLdJ trasoje vykdant žvalgymus. Jų metu žvalgant metalo detektoriais aptiktos 2 segės: XIV–XV a. datuojama plokštinė bei II–III a. datuojama pasaginė, puošta emaliu, sagčių dalių, 2 sagos ir kt. Žvalgant vizualiai suartame sluoksnyje pastebėta tamsios žemės dėmių su smulkia lipdyta keramika, apdegusių akmenukų. Ištyrus 8 1x1 m šurfus visuose armenyje rasta smulkių lipdytos keramikos fragmentų. Geomorfologiškai gyvenvietė įkurta tarp moreninių lankų buvusio platoko ir giloko glacialinio pažemėjimo R pusėje, ant siaurokos lėkštos pakilumos, kurią iš R–PR pusių juosė siauros ir seklios aukštesnio lygio fliuvioglacialinės nuosrūvos latakas, o iš V–ŠV – gerokai platesnė ir gilesnė glacialinė įduba stipriai raižytais pakraščiais.

ENIn 2020, an excavation (a total area of 746 m2) and field survey were conducted at Vilūnai Unenclosed Settlement II (Kaišiadorys district) at the future construction site of the GIPL connecting Poland and Lithuania. The settlement was identified during an April 2020 field evaluation when various copper alloy finds: 2 brooches (a 14th–15th-century flat brooch and a 2nd–3rd-century enamelled penannular brooch), buckle pieces, 2 buttons, etc. were discovered during a metal detector survey at the suspected Vilūnai Unenclosed Settlement II. A steep section, around 9–9.5 m high, of the former E–SE shore of a flowing lake was selected for establishing the settlement. The greater part of Vilūnai Unenclosed Settlement’s II cultural layer has been disturbed by ploughing, a 1–20 cm thick cultural layer horizon being recorded under the plough layer. The most widespread soil within the settlement’s boundaries is sandy loam and loam with small patches or pockets of purer sand and clay. 14 pits of anthropogenic origin, which contained abundant large potsherds, flint, charcoal; a pile of burnt stones, a brushed pottery pot, a late 18th-century coin, and blue glass beads were recorded at Vilūnai Unenclosed Settlement II. The majority of the flint found at Vilūnai Unenclosed Settlement II belongs to the last flint knapping technology, i.e. bipolar technique, which can date from the 16th/12th century BC to the 19th century. This flint could have been left by 1st–2nd-century members of the Brushed Pottery culture. About 10–20 pieces of flint: the end scraper, burin, point (?), almost all of the blades showing signs of use, and several flakes, can be ascribed to the Mesolithic – early Neolithic (9th–5th centuries BC).Based on the pottery and the results of the 14c dating of the charcoal, the Vilūnai Unenclosed Settlement II cultural layer dates to the 1st–3rd centuries.
