The mansion of Count Kushelev-Bezborodko is often called the Small Marble Palace. In St. Petersburg, this is the second residential building faced with marble (after the Marble Palace itself). The mansion acquired the existing appearance during its reconstruction by the architect Schmidt in 1857-1860. The main facade of the palace is designed in the style of the Italian Renaissance, but in general the mansion can be attributed to the architecture of eclecticism. Pink marble was used for decoration, a material unique for the Northern Capital.
Until now, only a few rooms of the Small Marble Palace, as well as the main staircase and some elements of windows and doors have been preserved in their original form. In the design of the interiors different styles and motifs can be seen: rococo, Renaissance and many others. The most notable halls are: White, Golden and Blue Drawing Rooms, the Grand Cabinet, the "Saxon Porcelain" living room.In the interior decoration of the palace the sculpture was widely used, including stone vases and caryatids.
Until December 2017, the European University in St. Petersburg was located in the premises of the Small Marble Palace. According to the latest data, the "Academy of Digital Technologies" is established in this historical and cultural monument of federal significance.
