At May 21st 2013 director of the mission visited trench of the polish archaeological expedition to estimate conservatory conditions of the object before start of the work-season. Unfortunately the trench meet with a partially degradation in the consequence of stealing of the safety net protecting banks of the trench. After intensive rains wide parts of the netless bank collapsed. As a result the trench needs, before start of the archaeological season, cleaning and several protecting preparations, because partly destroyed banks could be dangerous for people working in the trench.
