Conclusions. In the modern decoration of the Dormition Cathedral of the Kyiv-Pechersk Lavra, the Academicism painting (1897–1901) is presented in the apse of the southern nave (diaconicon). In this compartment, authentic fragments of academic compositions have been restored, the painting system has been revived based on archival photos, and some new academic compositions have been introduced to it. Mural paintings have been performed by artists under the supervision of Oleksandr Pashkovskyi in 2018–2019. They also performed new murals in the academic tradition in the altar part of side-altar of the Saint Apostle Andrew the First Called in the southern part of choirs in 2020–2021. In the northern part of the choirs, paintings have been started and then suspended in 2022. In the new murals complex the artists cite in extenso or in part the compositions of the late 19th – early 20th centuries using archival photos. The murals have been performed in mixed techniques: holy images in oil, ornaments in acrylic paints. The composition ‘Glorification of Theotokos’ differs in the techniques; it is painted with oil on canvas. In the modern interpretation, the cited compositions can keep or change the primary location. The colouring of the new murals is formed on the basis of fragments of authentic compositions. A considerable part of the decoration is occupied by stylised ornaments as well as in murals of 1897–1901. The new and primary mural painting combine same academic principles of visual language, iconographic and colour principles, thematic and plot lines. Same general thematic lines are such as Theotokos theme, the theme of the Last Judgment, the Christianization of Ancient Rus, images of the saints of Ancient Rus and saints associated with the Kyiv-Pechersk Lavra.
