The guard position The position is one of a chain of uprights (an upright structure that served as a defense and observation post), built at Mikve Israel in the 1940s, as part of the defense system of the "Security Road" that passed through Mikve Israel and the protection of the agricultural school.
The security road was paved with the outbreak of the War of Independence between the Ezra neighborhood in Tel Aviv via Mikve Israel to Rishon Lezion in order to stay away from the Abu Kabir neighborhood, Tel a-Rish and the Arab towns of Yazur and Beit Dajan, which attacked Jewish road users. It also served as a safe passage for convoys to Jerusalem, to the southern colonies coming from the Negev when they left Tel Aviv. In the mid-1960s, a plow was placed on the stand by the center of the mechanics branch, Yitzhak Cohen, one of the longtime employees of Mikve Israel, who educated thousands of graduates in labor values and agricultural development.
Combining the position with the plow symbolizes the values of the school that combines agriculture and security.
