Next to the modern building of Gymnasium No. 4, formerly known as the Real School, stands wooden house No. 3, preserved from the late 19th to early 20th century. This two-story residential building features wooden cladding and a stone basement. The windows are adorned with applied trim with trapezoidal lintels and pointed tops, while the gable is decorated with carvings. However, the layout and interior furnishings of the house have not survived.

The house was built in 1875. The estate occupied an entire block from Lekarskaya Street (now Volodarskogo) to Moskovskaya Street and also included a two-story brick house on Moskovskaya Street (No. 10). The owner of the estate was merchant Nikolai Alekseevich Alekseev, and after his death, it passed first to his wife and then to his children, who owned it until the revolution.

This house is an example of wooden residential architecture from the second half of the 19th century, featuring elements characteristic of ancient Russian architecture. It is the only wooden residential house in Penza with trapezoidal window openings. It is also a historical monument associated with the international movement. According to the decision of the regional executive committee dated September 28, 1987, the building is recognized as a cultural heritage site of regional significance as "Residential House (Wooden) of the 19th Century."

This house housed the committee of the party organization of foreign internationalists, the International Group of the RCP(b) (1918-1921), the German Revolutionary and Austro-Hungarian Councils of Soldiers' and Workers' Deputies (1919), as well as the K. Liebknecht Club, a library, and a hostel for internationalists (1920-1921).
