Jo'ara is a hill in the Menashe Heights. A small Palestinian Arab village existed on the hill until the 1930s. Between 1938 and 1948, it became the main military school for commanding officers of the Haganah and Palmach. After the establishment of Israel, the hill was used as a military base and officers school, and between 1970 and 2016 by the Youth Battalions' (Gad'na) pre-military programme. The base and its museum were closed down in 2016–2017.
