The village was located 26 km northeast of the city of Acre, on a rocky hill about 5 km south of the Lebanese border. It was linked by a paved road to Fassuta in the north and Tarshiha in the southwest. The road divided the town into an eastern and one western quarter, or haras, the eastern quarter being higher up.
The first part of the village name, Dayr ("monastery") suggest that the village might have had a monastery and a Christian population. However, in modern times the population was Muslim. According to the residents of the village, ancient artifacts from the Canaanite, Israelite and Roman period were unearthed in the Ottoman and British Mandate period.
In the Crusader era it was known as Cassie, and in 1183 it was noted that Godfrey de Tor sold the land of the village to Joscelin III. In 1220 Jocelyn III´s daughter Beatrix de Courtenay and her husband Otto von Botenlauben, Count of Henneberg, sold their land, including Cassie, to the Teutonic Knights.
Dayr al-Qassi was incorporated into the Ottoman Empire in 1517, and by 1596 it was part of nahiya (subdistrict) of Jira under the liwa' (district) of Safad, with a population of 132. It paid taxes on a number of crops, including wheat and barley, as well as on goats and beehives.
Victor Guérin visited in 1875, and he estimated that the village had 350 Muslim inhabitants. In the late nineteenth century, the village of Dayr al-Qassi was described as being situated on a ridge, encircled by fig trees, olive trees and arable land. It then had a population of about 200.
British Mandate era
At the time of the 1922 census of Palestine conducted by the British Mandate, Dair Wal Qasi had a population of 663, all Muslims, increasing in the 1931 census, when Deir el Qasi had a population of 865, still all Muslims, living in a total of 169 houses.
Later, Dayr al-Qassi was mostly Muslim but had a large Palestinian Christian minority. According to the 1945 census it had 1,250 inhabitants; 370 Christians and 880 Muslims. Together with the two villages of Fassuta (existent) and al-Mansura, the population was 2,300 and their total land area was 34,011 dunums. 1,607 dunams were plantations and irrigable land, 6,475 used for cereals, while 247 dunams were built-up (urban) land.
1948 and aftermath
During the 1948 Arab-Israeli War Dayr al-Qassi was defended by the Arab Liberation Army but the village was captured by the Israeli Army during its offensive Operation Hiram on October 30, 1948. The town's residents were expelled on May 27, 1949 and most migrated north into Lebanon.
Elkosh, established in 1949, occupies part of the village site. Netu'a, founded in 1966, Mattat, founded in 1979 and Abirim, founded in 1980, are also on village land. Netu'a is near the neighboring village of al-Mansura.
The Palestinian historian Walid Khalidi described the remaining structures on the village land in 1992: "A few stone houses still are used as residences or warehouses by the inhabitants of Elqosh. The debris of destroyed houses is strewn over the site. The school building stands deserted. Fig and olive trees and cactuses grow on the site."
In 2004, the "ruins of the village were removed by mechanical equipment."
