Unique findings, wells with wooden constructions and buckets made of lime bark in them, were detected recently in the Lieporiai 1 settlement near Šiauliai (in northern Lithuania). These objects were parts of an iron smelting site dated to the fourth to eighth centuries. Reconstructions of the well and the technique of producing lime bark buckets were made by B. Salatkienė and A. Šapaitė. A detailed description of the artefacts and their environment constitutes the first part of this paper, and the technique of reconstruction and producing lime bark buckets forms the second.
