The tallest wooden structure of the Lavra was a large multi-tiered bell tower on the southwest side of the Assumption Cathedral, built in 1669-1672 under Archimandrite Innocent Gisel. Judging by the images on the engraving in the book Akathists of 1677 and the 1695 map of Kyiv by I. Ushakov, it was 30 to 40 meters high. The structure was an octagonal five-tiered tower with large bells on the third, open tier, and a faceted fourth tier. A light drum topped with a cross rose above it. The first and second tiers were covered with boards, and the domed roofs of the upper tiers were shingled. Most likely, the building was dismantled in the late seventeenth and early eighteenth centuries, when the process of replacing wooden monastery buildings with stone ones began.

The remains of the bell tower foundations were discovered during archaeological research in 2002 (excavations by S. Balakin). The masonry was recorded at a depth of 0.3-0.4 m from the modern surface and traced over an area of 4.5×4.0 m. The foundations, 0.9-0.95 m thick, consist of two tiers of large rubble blocks. The upper plane of the lower tier is leveled with a layer of broken brick and lime mortar.

Perhaps these foundations belonged to the first stone bell tower designed by architect D. Aksamytov, which was supposed to replace the original wooden one. Construction was suspended after the architect's death in 1707.
