The mound called Kleboniškis and Pekelka, otherwise known as Lentainių or Lantainių, is dated back to the 1st millennium – the early 2nd millennium. It offers an inspiring view of not only nature of Kaunas district, but also of the city panorama.
It is believed that a wooden castle enclosed by a defence wall used to be here. For additional defence, terraces were formed on south-eastern and south-western slopes. The castle was also protected by steep slopes 30 m high.
Remains of the settlement dating to the 2nd half of the 1st millennium – the 14th century, fireplaces, sharpener, rough and thrown pottery, etc. have been found. Nearby, Radikiai necropolis dating back to the 2nd – 16th century is situated.
