ENIn reconstructing the bell tower of the Church of St John, excavations were conducted in its basement and outside near its foundations. The architectural investigation established that the bell tower was built in 1610–1615 on the remains of a 15th-century masonry building. Authentic brick stairs from this period, the continuation of which is in the masonry of the tower’s E wall, were discovered in the basement. A fragment of a ceramic tile floor dating to the late 16th – early 17th century was found. It was determined that the cultural layer outside the tower near its S part is barely 70–80 cm deep; v. Jono Street was built in a higher location. The trench excavated outside the E wall of the tower’s basement contained the remains of many masonry constructions and structures. The remains of the wax (candle) workshop that stood here during the 18th–19th centuries and the remains of masonry structures dating to the first half of the 17th century were discovered near the S wall. One of these structures is the foundation of the masonry fence that enclosed the yard of the Church of St John on the S in the 17th–19th centuries.
