ENIn 2004 an area of 20 m2 was investigated in the cellar o f the third block of the building complex located at the T. Kosciuškos Str. 3 (Vilnius) called the Horains’ House. A fragment of floor paved with stones and a thin cultural layer of about 30 cm containing finds of the 17th (16th?)- 20th century were found. Artefacts collected during the survey comply with historical information saying that the building was built in the mid 18th century. Nevertheless some finds and remains o f earlier foundations imply that the site could have been inhabited already in the 16th-17th century.
