מוזיאון המשטרות הפוליטיות ברוסיה, museum of political police on Gorokhovaya Street, Saint Petersburg, Russia

The Museum of Political Police is housed in a late 18th-century building on Gorokhovaya Street in Saint Petersburg. It displays documents, objects, and reconstructed spaces across several galleries that tell the story of state security agencies across different periods of Russian history.

The mansion was built in 1788–1790 by Giacomo Quarenghi for Baron Fitingof, physician to Catherine II; the city bought it in 1803 and rebuilt it under A. A. Mikhailov, then again in 1876 under K. K. Anderson. From 1804 it housed the provincial government offices, and from late 1877 the city governor Fyodor Trepov, who added a fifth floor. From December 1917 to March 1918 the Cheka sat here under Dzerzhinsky; the current museum grew from a 1974 memorial office of Dzerzhinsky and became the Gorokhovaya, 2 branch in 1994.

The building's name in the museum's own title, "Gorokhovaya, 2", comes from its address. The first museum here opened in 1925–1929 by order of Felix Dzerzhinsky and was open to all members of the Communist Party; today's museum grew from the reconstructed office of Dzerzhinsky opened to visitors in 1974.

The museum is open on most days of the week, though hours may vary by season, so it is worth checking current times before your visit. Tours can be arranged in advance if you want detailed explanations of the exhibits and building.

The building's courtyard side gained a fifth floor in the late 1870s to house the official apartment of city governor Fyodor Trepov. On 24 January 1878, Vera Zasulich shot and wounded Trepov in this building. Later, the first departmental VChK-OGPU museum opened here in 1925 by order of Felix Dzerzhinsky, accessible only to Communist Party members.
