Since 1997, the lakes of eastern Lithuania have been studied by Zenonas Baubonis, Mantas Kvedaravičius, Rokas Kraniauskas, Elena Pranckėnaitė, and Giedrė Motuzaitė. In 1999–2000, on the northern shore of Lake Luokesai, at a depth of 1.5–2 m, archaeologists discovered the first pile-dwelling settlement (800–400 BC) of the Bronze Age in Lithuania. The settlement is attributed to the Brushed Pottery culture. In 2001, a second settlement was found on the southern shore of Lake Luokesai.
The 1st Luokesai Settlement consists of a rectangular residential complex, surrounded by crescent-shaped defensive fences. In the northern part, the fortifications were tripled, as this section of the settlement was closest to the shore and likely the main point of access. Archaeological excavations uncovered a cultural layer, 40–110 cm thick, rich in archaeological finds. It contains 7–8 horizontal construction layers of wooden structures and approximately 350 vertical piles.
The 2nd Luokesai Pile-Dwelling Settlement is located on the southern side of Lake Luokesai, in a horn-shaped shallow area. Beyond the shallow zone, there is a sudden drop of 9 meters. The remains of the second settlement consist of a single layer of horizontal wooden platform elements and approximately 300 vertical piles.
