The ancient hillfort hidden in a field, Lithuania

Antatilčių I piliakalnis is one of two hillforts in the southern Pakraštyje region of Ukmergė County, Lithuania. The hillfort is found among fields, northeast of Plaštakos and Siesarties villages, near the Plaštakos River. The oval mound, measuring 52x17 meters in size and 3 meters high above the surrounding ground, is surrounded by a ditch 25 meters wide, 2 meters deep, and 15 meters wide at the top. The ditch is covered by a 3-meter-high stone wall, arranged in a herringbone pattern.

The wall is 14 meters high. The hillfort is thought to have been constructed during the 2nd century AD, although it was largely destroyed by the growth of a large tree, whose roots have damaged parts of the hillfort. Archaeological excavations conducted in 1987 by the Lithuanian History Institute uncovered remains of an ancient culture that included pottery dating back to the 1st century AD. Only about 3% of the original structure is still visible, but what remains still reveals a rich history.
