Located about 4 km east of Petah Tikva, near the Yarkon river, it falls under the jurisdiction of Drom Hasharon Regional Council.

[1] The kibbutz is named for the three workers from Petah Tikva who were accused of espionage during World War I (Palestine was then under the rule of the Ottoman Empire), and were sent to a prison in Damascus.

[2] The kibbutz was founded on 1 May 1925, by a group from the Zionist pioneering HeHalutz movement originating in the city of Klesów in Poland (now Klesiv, Ukraine).

[citation needed] In 1953 Givat HaShlosha was moved to its current position; on the land of the newly depopulated Palestinian village of Majdal Yaba.

In 1952, an ideological dispute led to the construction of a brick wall in the center of the dining hall to separate the two groups and finally the establishment of a new kibbutz, Einat near Rosh HaAyin.
