WATCH: British Mandate-era arms cache found in Hod Hasharon synagogue

Two Israeli curators on Thursday stumled upon an arms cache dating back to the British Mandate at a Synagogue in Hod Hasharon.

The weapons, which included grenades and bullet casings, were apparently stored in the building by the Hagannah Jewish militia.

Simcha Klein and Aviva Even-Hen, curators of the museum dedicated to the history of Hod Hasharon, found the arms while they were tidying rooms in the synagogue, which was crammed full of documents, pictures and old maps dating back to the beginning of the Zionist enterprise.

"While searching the rooms, we came across one small tin box that contained grenades, and another that contained dozens of bullet casings," Klein said. "We then called the police, and sappers came and removed the weapons from the building."

The curator added that she hoped that the museum would be able to display the munitions as an historic exhibit

Klein said that during the British Mandate, the synagogue used to serve as a shelter from Arab rioters, and therefore has long and narrow windows, and slits for firing. These slits apparently made the synagogue an ideal location for stashing the weapons.
