Two examples of Constructivist architecture I found in my wanderings in St. Petersburg:
Меняевский рынок – Жилой дом / Menyaevskii market – Housing
Original market was built in 1883, and was later converted into housing in the Constructivist style in 1932-1933, with some elements of the original building remaining.
Здание Кировского райсовета / Kirovsky Town Hall
1931-1935
