LT2020 m. Pakertų neįtvirtintoje gyvenvietėje (Kaišiadorių r., Žiežmarių apylinkės sen.) buvo atlikti detalieji tyrimai LLDJ dujotiekio darbų vietoje. Gyvenvietė lokalizuota 2020 m. ankstyvą pavasarį, kai A. Kuncevičius su tyrėjų grupe vykdė žvalgomuosius tyrimus tiesiamo dujotiekio trasos vietoje. Pakertų kaimo laukuose žemės paviršiuje aptikta neaiškaus laikotarpio lipdyta lygi šukelė. 2020 m. balandžio 20 d. šios šukės radimo vietoje ir aplinkoje – daubelėje į Kertaus upelį – ištirta 11 kasinių, kiekvienas 50x50 cm dydžio. Kasiniuose 2 ir 3 po armeniu aptiktas 35–40 cm storio pilkas kultūrinis sluoksnis, rastos kelios lipdytos brūkšniuotos ir lygios keramikos šukės. [...] [p. 117].
ENIn 2020, an excavation was conducted at the GIPL construction site at the Pakertai Unenclosed Settlement (Kaišiadorys District). The settlement was identified during an early spring 2020 field evaluation when a 35–40 cm thick grey cultural layer containing several sherds of hand built pottery with brushed and smooth surfaces was discovered. During a field survey of the Pakertai manor site and a regional road running past its W edge, 14 various sized pits, two sunken hearths, and 2 small areas with a dark cultural layer were recorded in the clayey sterile soil. All of the surviving areas of the settlement’s cultural layer in a 590 m long strip on the grounds of Pakertai Unenclosed Settlement were numbered from I to VII (beginning in the E) and excavated, a total of 1102 m2. An archaeologically valuable cultural layer containing archaeologically valuable finds: sherds of hand built pottery with smooth and brushed surfaces preliminarily datable to the 2nd–4th centuries, flint blades and flakes, spindle whorls, slag, clay daub, and animal bones was discovered in areas I (W part) – VI and excavated. No archaeologically valuable cultural layer was discovered in the E part of area I or in area VII of Pakertai Unenclosed Settlement. Based on the archaeological finds and the results of the 14C testing of the charcoal, Pakertai Unenclosed Settlement dates from the Middle Mesolithic to the Old Iron Age (1st–4th centuries). An archaeological cultural layer from 17th– 18th-centuries Pakertai manor was also discovered in area VI.
