The grave of the renowned doctor Fyodor Petrovich Gaaz has become a pilgrimage site for former prisoners. However, it is not only they who come here, but also everyone who shares the motto inscribed on his tombstone: "Hasten to do good!"

The tombstone stands out with its appearance: it is a large gray stone with a cross on top, resembling Golgotha, the hill where Jesus Christ was crucified. The uniqueness continues in the details: the grave's fence is adorned with chains that resemble shackles.

These chains are authentic, preserved since the nineteenth century. They can be touched, lifted, and one can imagine the heavy burden carried by prisoners along the Vladimir tract. These "Gaaz chains" weigh 7 kilograms, whereas previously, prisoners wore chains twice as heavy, 16 kilograms.

Gaaz invested all his resources into the cause that became the meaning of his life. He truly hastened to do good, as the inscription on his tombstone states. He had no family and devoted himself entirely to his work. The doctor’s funeral was paid for by the state, but he was not alone on his final journey; nearly 20,000 people followed the coffin. This was the most massive funeral at Vvedensky Cemetery. The monument at his grave was erected with funds from those whom Gaaz once helped.
