The mansion of V.N. Yakovenko, "Professor's House"

Built in 1887 in the Neo-Renaissance style, architect Vasily Ivanovich Shaub (a Russian architect of German origin, Karl Albert Emil Wilhelm Shaub), together with his son Vasily Vasilyevich Shaub. The Yakovenko family owned the mansion for 20 years.

At the beginning of the 20th century, the building was transferred to the Agricultural Courses (a building was constructed next door for them) – the Professors' House, and in Soviet times – to the Naval College. Now the mansion belongs to the Administrative Department of the President of Russia, like many other buildings on Kamenny Island. By the way, in the neighboring house No. 22, at the dacha of F.I. Dolivo-Dobrovolsky, A.S. Pushkin lived with his family from 1834 to 1836. Here he wrote the poem "I have erected a monument to myself not made by hands..."
