[16] In 1875, Victor Guérin found "twenty united Greek families" living in the village which had been built on an ancient site, of which there were many remains.

[17] In 1881, the PEF's "Survey of Western Palestine" (SWP) described Fassuta as "a village, built of stone, containing about 200 Christians, situated on ridge, with gardens of figs, olives, and arable land.

[21] In the 1931 census, the combined population of Fassuta and Mansura was 507 Palestinian Christians and 81 Muslims, living in a total of 129 houses.

In December 1949 the Israel Defense Forces devised a plan to create a 5–10 km Arab-free zone along the Lebanon border by ordering those who remained in Fassuta and five other villages to leave.

In April 2023, a resident of Fassuta was injured in a rocket attack from Lebanon attributed to the militant group Hamas.

[33] In 1875, Victor Guérin found "numerous cisterns, a great reservoir, vestiges of many ruined houses, fine cut stones marking out floors, and a dozen of winepresses nearly perfect.

Worked in the rock, they consisted of two compartments, one larger, in which the grapes were placed, and one smaller and lower down, in which the juice was received."
