Less than 8 months (including preparations from November 2014 to August 2015), comprehensive and demanding construction and restoration works were carried out by the DORACO Construction Corporation for one of the oldest churches in Warsaw. At the same time, as part of the same works, the former parish building was rebuilt and adapted to the needs of the Archdiocese Museum. The scope of activities related to the revitalization of the Cathedral, which in 1980 was entered on the UNESCO World Cultural Heritage list, included all electrical, telecommunication and sanitary installations and most of the temple’s rooms.
The degree of advancement of the renovation and the nature of the works carried out was very complex and detailed. Most of the monuments have undergone specialist conservation and renovation works. In addition, the energy efficiency of the temple has been increased by making low-power installations such as church interior lighting and electric heating.
During the works, historic elements were discovered that the cathedral will be able to show to visitors. During the earthworks in front of the Cathedral, the excavation of, among others, a crypt with an arched vault, dating back to the 19th century, and a stone bench with a diameter of 0.5 m to 3 m – constituting the foundations of the former cathedral tower.
The investment was implemented under the project: “Treasury of Cultural Heritage – Cathedral Basilica and Museum of the Archdiocese of Warsaw”, co-financed by the European Regional Development Fund and the Ministry of Culture and National Heritage.
