Bolshaya Podyacheskaya St., 5, Saint Petersburg, Russia, 190068
The address is indicated in Dostoevsky's "residence permit": "3rd part of the 109th quarter. No. 256, in the apartment, January 17, 1848." The address, given again in the old, "continuous" numbering of the 3rd Admiralty part, was house No. 6 at the end of the 1840s. The modern address is Bolshaya Podyacheskaya Street, No. 7, and the house still stands. Dostoevsky lived at this address from January until the end of May 1848, when he moved with his brother Mikhail's family to Pargolovo for the entire summer. This address has never before been mentioned in research literature. It may seem that the very fact of Dostoevsky living in 1848 on Bolshaya Podyacheskaya contradicts the widely known information that from 1847 to 1849 he lodged in Shil’s house on Voznesensky Prospect. However, besides the police registration in the writer’s "residence permit," there are other confirmations of this.
At the end of September 1847, the retired Dostoevsky arrived from Reval to Petersburg and settled with his brother in Shil’s house. It can be assumed that living together in one room in furnished quarters was cramped for the brothers, and at the beginning of 1848 they moved to a new apartment. This event should be linked to the recollection of Dr. Yanovsky, who wrote: "As I remember now, on one Sunday, Fyodor Mikhailovich, leaving me at eleven in the morning, said goodbye and invited me to his housewarming. At that time, Mikhail Mikhailovich, having retired, arrived alone without his family and settled together with Fyodor Mikhailovich in Petersburg. Following the invitation, I came to the Dostoevskys..." In relation to the police registration in the "residence permit," this "housewarming" can be understood precisely as the brothers’ relocation to the new address — Protopopov’s house on Bolshaya Podyacheskaya.
Later, in the first decade of April 1848, Mikhail Dostoevsky’s wife Emilia Fyodorovna arrived from Reval with the children, and they settled as a family in the merchant Neslind’s house on Nevsky Prospect, No. 109 (modern No. 104).
