The first order for the improvement of the Russian cemetery in Piraeus, which had existed earlier (the earliest burial dates back to 1844), was issued by Queen Olga in 1891. According to church records, more than 90 people were buried here before the revolution. In 1907, on the anniversary of the Battle of Navarino, by the order of Queen Olga, the municipality of Piraeus allocated additional plots of land by the northern wall of the cemetery. A year later, a 30 square meter plot for the burial of British individuals, mainly sailors who served in Piraeus, appeared next to the Russian cemetery. English soldiers who died in World War I were also buried here. Both cemeteries were fenced.

In 1883, by the order of Queen Olga, the remains of Russian sailors who perished during Count A. Orlov-Chesmensky's Archipelago Expedition in the 18th century, as well as those who fell in the Battle of Navarino in 1827 and sailors and officers who died abroad while serving in the Russian fleet in Greece, were collected throughout Greece. They were reburied in a special section of the cemetery in Piraeus, where a mass grave was created. The following year, a monument to the Russian sailors, made in Russia at the expense of Emperor Alexander III, was erected at this grave.

Greek newspapers described the funeral of Ivan Mazin, who died on September 28, 1895, as follows: "Russian non-commissioned officer Ioannis Mazin from the crew of the ship 'Dzhigit', assigned to Kronstadt, passed away in the Zanion hospital. The funeral service took place at 4 PM. A Russian archimandrite arrived from Athens. The commander of the ship 'Chernomorets' Mr. V.Ya. Bal and other Russian and Greek officers in uniforms and without headgear were present. A military band led the mourning procession. Many Russian sailors and local residents accompanied the deceased to the new cemetery where Russians are buried."

The historic cemetery in Piraeus has been preserved, albeit with losses. It bears the official name "Russian Cemetery named after Queen of the Hellenes Olga," reminding us that it was established, like the naval hospital, with the funds of Olga Konstantinovna.
