Skarżysko-Kamienna is an important railroad junction, with two main lines (Kraków – Warsaw and Sandomierz – Koluszki) crossing there.

In 1922 the government of Poland decided to build an ammunition factory in Kamienna, to be called Państwowa Wytwornia Uzbrojenia Fabryka Amunicji (P.W.U.

Fabryka Amunicji, "National Armament Factory - Ammunition Plant") It began production in 1924 supplying munitions to the Polish Army.

[4] Following the September 1939 invasion of Poland by Germany, which started World War II, Skarżysko-Kamienna was under German occupation until liberated by the Soviet army in January 1945.

The ghetto was liquidated in October 1942, with some inhabitants judged fit for work moved to the factory labour camps (about 500 out of 3000), and the rest were transported to Treblinka.

[7] There are several known cases of Poles, who were either executed on sight or imprisoned in the local prison and deported to concentration camps for rescuing and aiding Jews.

[8] In April 1942, the Germans founded the Stalag 380 prisoner-of-war camp, which several months later was relocated to Oppdal and Dombås in German-occupied Norway.

[5] On January 18, 1945 the town was liberated and restored to Poland, although with a Soviet-installed communist regime, which remained in power until the Fall of Communism in the 1980s.

The remaining Jews left Poland,[12] except for Dr. Zundel Kahanel and his wife Bima who spent the rest of their lives in the city.
