At the cemetery there are three rectangular, framed and covered with concrete slabs mass graves, with plaques:
The first plaque on the first grave reads: "GLORY TO THE MEMORY / OF JEWISH POPULATION / WHO FELL FROM THE HANDS / OF HITLERITE MURDERERS.”
The second plaque on the first grave reads: “PLACE OF ETERNAL REST OF 800 VICTIMS / POLISH CITIZENS OF JEWISH NATIONALITY / MURDERED BY THE HITLERITE FORCES ON THE DAYS 4-13 SEPTEMBER 1942 / GLORY TO THEIR MEMORY”
The second mass grave has a plaque with a poem that reads: “THIS IS WHAT NEEDS TO BE CARVED IN POLISH MEMORY LIKE IN STONE OUR COMMON HOUSE WAS DESTROYED THE SPILLED BLOOD MARKS OUR BROTHERHOOD. WE ARE CONNECTED BY THE EXECUTION WALL, BY AUSCHWITZ AND DACHAU , EACH UNKNOWN GRAVE AND EVERY PRISON BAR.
The third mass grave has a plaque that reads: TO OUR CO-CITIZENS AND JEWISH MARTYRS. THE INHABITANTS OF WOLBROM.
In those three mass graves, there are from 600 to 800 Jewish victims buried.
In September 1939, just after the Germans invaded Poland all Jewish residents of Wolbrom were expelled walking in the direction of Zawiercie. The marching column stretched for few kilometers, the walk took up to 3 days and was accompanied by regular German soldiers mockery and brutality. Most of those who survived were made to return to the city. In autumn of 1941, the Germans administered a ghetto, where almost 8,000 Jews were concentrated, including about 3,000 deportees and refugees. The ghetto borders were sealed in the spring of 1942. Liquidation of the ghetto in Wolbrom began in September 1942. The German police and Ukrainians walked all Jews to the railway station, where the selection was carried out. About 600 old and weak people were taken to the forest gorge, where they were shot and buried in mass graves. The Jews remaining at the station were loaded into cattle wagons and transported to the death camp in Bełżec. Several hundred fit and young men were selected and transported to labor camps. After the liquidation of the Jewish community in Wolbrom it was the desolate Jewish cemetery which became the place of executions of people who were denounced or came out of hiding. From mid-September 1942 to the end of 1944, nearly 400 Jews were shot in this way. Only 300 Jews from Wolbrom survived the war, most of them emigrated just after the war finished.
