Underground Bullet Factory

Tour Israel’s Hidden Bullet Factory – The Ayalon Institute

The Ayalon Institute or “Machon Ayalon” in Hebrew is well worth a visit next time you’re touring in Central Israel! The Museum is located on the site of an underground bullet factory created by Jewish pioneers in preparation for the War of Independence.

The Story of the Ayalon Institute

During the entire period of the British Mandate (1917-1947), Jewish paramilitary groups such as the Haganah, Irgun and Palmach were outlawed. This made it very difficult for the Jewish inhabitants to prepare themselves for the war that was sure to come when the British would leave. One of their problems was that they didn’t have enough ammo for their weapons.

In 1945 the Haganah decided to create their own factory to produce ammo. The problem was how would they hide it from the British? The solution they came up with was to build a new Kibbutz and hide the bullet factory underground! The code name for the bullet factory was “Machon Ayalon” – The Ayalon Institute.

To disguise the noise from the factory, they set up real factories on top of the hidden bullet factory. These included a laundry and bakery. They only ran the underground factory at the same time as the above ground factories were working in order to hide the noise. They were so successful that the British soldiers even sent their uniforms to the laundry to be washed and starched!
