Russia plans a new pretrial detention center outside Moscow. With room for 4,000 detainees, it would be the largest in the country.

Russia is constructing a new pretrial detention center outside Moscow, which will be the largest of its kind in the country. Located in the Solnechnogorsk district of the Moscow region, the facility will have a capacity of 4,000 detainees and span over 42 hectares. The center will feature separate buildings for men and women, as well as additional structures for those with tuberculosis and criminal gang leaders considered a negative influence on other detainees.

Federal Penitentiary Service employees will occupy three apartment-style buildings within the complex. Construction will commence near the 71-kilometer marker on the M-11 highway, between the villages of Shapkino and Ozhogino, with an estimated completion date of October 2031. The initial bid for the construction contract is valued at 37.8 billion rubles.

Prime Minister Mikhail Mishustin issued an order for the project in 2022, and it received state expert approval earlier this year. Currently, "Kolpino," also known as "Kresty-2," holds the title of Russia's largest pretrial detention center, having been built in a St. Petersburg suburb in 2017 after a decade-long construction process.
