The paper presents results of the concrete quality tests in the upper ring of the Centennial Hall dome inWroclaw, carried out as part of the renovation works of this facility. The tests included the determination of the actual compressive strength of concrete on the basis of core drilling tests and the "pull-out" measurements, as well as determination of the water absorption of the tested concrete and assessment of its carbonation degree. The obtained results showed that the tested concrete is characterized by surprisingly good physical and mechanical properties. Its strength parameters correspond to the current requirements for the C20/25 strength class, and the high quality of the tested concretewas also confirmed by the results of thewater absorption determination, the values of which were close to 5%. The obtained results are, on the one hand, a unique source of information about the quality of concrete from the beginning of the 20th century, and, on the other hand, allow for the assessment of the conditions of durability of this material after a century.
