The neighborhood was established in 1949 to absorb demobilized soldiers after the
1948 Arab–Israeli War. In 1954, Tel Aviv municipality donated a plot of land on Golan Street in Ramat HaHayal, dubbed "Shikun Shanghai", to members of the Jewish community from Shanghai, China, who left during the final stages of the
Chinese Civil War. Until 2010, it was widely assumed that the neighborhood had been named after the
Jewish Brigade and its name was written in Hebrew (
lit. Jewish Brigade Heights), including in official municipal signs. The mistake was corrected by the municipality in 2010. Many Israeli high-tech companies, among them Nisko,
RAD Data Communications,
BMC Software,
Comverse Technology and
Radwin are located in Ramat HaHayal. The offices of the Israeli television broadcasting company
Keshet are in Ramat HaHayal. In 2002, a monument dedicated to the Swedish diplomat
Raoul Wallenberg was erected at the intersection of Raoul Wallenberg and HaBarzel streets in Ramat HaHayal.
Assuta Medical Center, Israel's largest private medical provider, moved from central Tel Aviv to a new compound in Ramat HaHayal. The upscale facility, with 16 operating rooms, is located on HaBarzel Street. ==Archaeology==
