Sukhanovo Prison

Sukhanovka, short for Sukhanovskaya osoborezhimnaya tyur'ma (Russian: Сухановская особорежимная тюрьма) 'Sukhanovo special-regime prison,' was a prison established by the NKVD under N. I. Yezhov in 1938 for "particularly dangerous enemies of the people" on the grounds of the old Ekaterinskaia Pustyn' Monastery near Vidnoye, just south of Moscow.

Known officially as Special Object 110 (Russian: Спецобъект № 110), it was said to be worse than the Lubyanka, Lefortovo, or Butyrka prisons in Moscow itself.

[4] NKVD head N. I. Yezhov was imprisoned in Sukhanovka beginning on 10 April 1939 and was interrogated there by the Main Military Procurator, N. P. Afanasyev.

[5] Yezhov's long-time colleague Filipp Goloshchyokin was also held under "heavy interrogation" in Sukhanovka for a period of 12 months until he was transferred back to Butyrka, and subsequently to Kuibyshev where he was shot in October 1941.

[8] Alexander Dolgun, a Polish-American worker imprisoned in the Gulag in the late 1940s, was sent to Sukhanovka twice, and is one of the few known to have survived the experience without losing his mind.
