Historical background

: (the Haganah symbol was taken from one of the signs on the site)
The largest and most institutionalized military organization among the three undergrounds. The Haganah was established in 1920 to provide protection against Israeli Arab attacks on the Jewish settlement . During World War II WWII, the organization cooperated with the British against the threat of a Nazi invasion of Israel, but at the end of the war, the organization directed its efforts against the British rule in the Land of Israel. The organization operated until the establishment of the State of Israel in 1948, and formed the basis for the establishment of the IDF after the establishment of the state.

Defense of the Hebrew settlement
The main activity of the "Hagana" organization in the 20s and 30s of the 20th century, centered on the defense of the Jewish settlement, as well as training and building the organization.
The Hagana was greatly assisted during this period by the "Notrim" - the police of the Hebrew settlements within the British police. The monitoring stations were throughout the country, thus in Rishon Lezion , Netanya , Holon , Petah Tikva and many other places.

Training centers
The training centers, called Makalim (learning places), were usually in schools. In these centers, the trainees acquired knowledge in the use of light firearms, fieldcraft, topography, face-to-face combat, first aid, communication, and more.
Some of the training centers, as mentioned, were located mainly in schools: Netzah Yisrael , Tschernihovski , Beit Strauss , Balfour , Tahkamoni , Balfour Gymnasium , Tel Hai , Hosmasa (Holon) , , Geula , Geula (Commercial School) , Ahad Ha’am , Kalischer
At the Tel-Nordau school, the Haganah’s women’s battalion trained, which later became the Chen (Women’s Corps of the IDF)

Weapons production
Starting in the 1930s, the Haganah began to engage in the procurement of weapons as well as their production (including ammunition for purchased weapons).
Yehuda Arazi started the shopping spree in Poland in 1936.
The production of weapons began as early as 1933 at the "Water Institute" in Givatayim , where a workshop was established for the production of hand grenades.
In 1936, part of the production of weapons moved to Tel Aviv, at "Institute A" which operated on the seashore of Tel Aviv inside a leather processing factory, hand grenades were initially produced, and years later the "Sten" submachine gun was also produced there. In addition, weapons are manufactured (grenades and parts for the machine gun "Sten") in a place called "the store" (near the old central bus station of Tel Aviv)
Simultaneously with the establishment of Institute A, factories were established for the production of weapons in Naan , in Rehovot Winery , in Rishon Lezion Winery , Haskelberg House in Rehovot And in 1938 "Institute B" was established in Tel Aviv where mortars were produced
In 1942, the base was established for what later became Israel’s military industry. In the port of Tel Aviv (the exhibition grounds) the "HaSnif Institute" was established where submachine gun parts were produced , "Yosef Institute" in Kfar Vitkin , "David Institute" in Gan Haim , "Sela Institute" in Tel Mond .
Other places where weapons were produced were in Tel Yitzhak ("Bamifne" Institute, a chemical plant) , the Reading I power plant (Tel Aviv) In which was also the technical office of Ta’as (military industry) .
The main place where weapons were produced was the "Ayalon Institute" (Rehovot), a factory that after the War of Independence was transferred to the military industry .

The mortar was developed by David Leibowitz who was a teacher at the agricultural school "Mikve Israel" in whose blacksmith shop the mortar was developed . The first experiments with mortar were done in the sands of Holon . Davidka was used for the first time in the attack on Jaffa in early 1948 . The main success of the Davidka was in the big noise it made. The Davidka that was used by the Defense Forces in the occupation of Katmon, Mount Zion and Camp Allenby in Jerusalem was commemorated in the square named after it
