Destroyed during the war years, the White Tower was restored in the 1990s: the historical volume-spatial solution was recreated; façade architecture, including carpentry infills and elements of metal decor and sculptures of knights; rough interior finishes completed.
Repair and restoration work was suspended in the period 2000-2011.
In 2013, work was completed on the restoration of the facades and historical brickwork of the walls and vaults of the basement floor, the reconstruction of the interiors of the premises, the repair of engineering networks and the installation of engineering and security and fire equipment, after which the museum's interactive center was opened in the building.
During the operation of the building, defects in the waterproofing of terraces and balconies were revealed, which leads to regular soaking and, as a result, the appearance of facade defects.
In 2019, CJSC "Restoration Design Research Center "SPETIALIST" developed a working project for the preservation of the cultural heritage site "White Tower".
