There has been a marked increase in the number of tourist routes in Moscow region. Numerous noble estates represent an important part of the region’s cultural assets. In Moscow region, there are lots of former estates of prominent families of the Russian Empire: today many of these properties are in ruins. Manor Sennitsy situated in Ozyory district of Moscow region is one of such gradually decaying cultural monuments with a rich history. This study analyzes a set of sources, on the basis of which the author creates a virtual 3D-reconstruction of manor Sennitsy in the period of late 19th – early 20th century when it was owned by the family of Count F.E. Keller. The source base for the study is very diverse: plans, drawings, cartographic materials, photographs, inventories of property, construction cost estimates. The author describes gradual process of 3D-modelling, in the framework of which softwares SketchUp and Twinmotion were used. The article pays attention to the history of Sennitsy’s construction and its owners. Reconstruction of buildings of the Sennitsy manor complex allows to visualize an image of the destroyed monument of culture, as well as to demonstrate high potential of using 3D-modelling methods in history. This study is carried out within the framework of the Project of reconstruction of appearance of the noble estates of the Moscow region, supported by the Department of Historical Information Science of the Faculty of History of M.V.
