Pugachev's cell

The prison cell converted from the gun casemate is on the photo. In the center the manhole to the dungeon is seen.
There were no Pugachov himself, but his family members - he's two daughters, son and wife - Sophia Dmitrievna Pugacheva and he's mistress - Ustinja Kuznetsova. Pugachev's family was put into the fortress "without specifying the term" and was held there more than 50 years.
