And I quote….

 

In 1999-2000, during the archaeological and restoration work, the builders removed two-meter land strata throughout the entire space of the Luzhetsky monastery.

 

…we present a photograph of 2000 taken in the Luzhetsk monastery after the removal of the upper layers of the earth. The thickness of the removed layers is clearly marked by a dark shaded strip running along the bottom of the monastery cathedral.
