On the territory of the church, a chapel "All-Merciful" was built to house the famous image of the Mother of God, which is believed to help in healing from cancer. The construction was funded by donations and was completed in May 2008. By the blessing of the ruling bishop, on June 28, 2008, the rector of the church, Archpriest Mikhail Grigoriev, conducted the consecration of the chapel.

The chapel "All-Merciful" is located next to the oncology dispensary, so that patients can pray to the Most Holy Theotokos. Daily, a service with an akathist is held in the chapel before the icon of the Mother of God "All-Merciful," dedicated to the healing of cancer patients and for the health of all who suffer mentally and physically.
