The building at Ostozhenka, 36 in Moscow, known as the House of the Sergievsky Orphanage, seems to have been transported from a fairy tale reality. It was constructed by 1890 according to the design of architect Yakov Ivanovich Antonov.

The facades of the building are executed in a pseudo-Russian style, sometimes referred to as Russian ornamentation. The decor clearly showcases elements of Moscow architecture from the 17th century with exquisite details and intricate patterns of window frames on the second floor. The main facade faces Eropkin Lane. Initially, the building was three stories high, as seen in old photographs, but a fourth floor was later added. The wing of the building was reconstructed in 1896 according to the design of Nikolai Eduardovich Pelitsa.

Originally, the building was intended for the Council of Children's Orphanages, known as the Sergievsky Orphanage, named after Grand Duke Sergei Alexandrovich. The society was founded in 1842 and was under the patronage of Empress Maria Feodorovna for some time. All children's orphanages were part of the system of the Office of Institutions of Empress Maria, whose history begins with the office of Empress Maria Feodorovna, the wife of Paul I, who took under her management the Moscow and St. Petersburg educational homes along with all their institutions starting from May 2, 1797.

In the early 20th century, a children's hospital opened in the building, where treatment and care were completely free. During the Soviet era, a 'Mother and Child House' was established based on this medical institution.

Today, the building at Ostozhenka, 36 houses classrooms of the Moscow Linguistic University (MGLU).
