ENIn 2002 in the Baltadvaris castle site (Molėtai district) on both sides of the defensive rampart two areas (the total area - 51 m²) were explored. Outside the defensive rampart, a ditch, 1 m deep and up to 2 m wide was found where the earth for the rampart was taken off. Among the finds there were fragments of hand-thrown pottery and tiles dated to the 16th-17th centuries.
