Bolesław Szabelski Aula, located on the second floor of the building, required conservatory and repair works. Under the supervision of the monuments conservator, layers of old paint have been removed in order to reveal the beautiful polychromies on the walls. We have dismantled the stage platform and the structure where the old organs were located, and later we have reconstructed the stage, fronton and the new support structure for the organs. Renovated and cleaned glass windows, with missing elements supplemented, have been re-installed in the building windows.
