The Reason Behind The Name: It is said that the origin of the name is due to the distortion of the Canaanite word "Sin," which is the moon, so the meaning is the eye of the moon, and in the Middle Ages, it was mentioned as "Ainesins."

Ein Sinya

The village is situated along the historic road connecting Jerusalem and Nablus, and it is renowned for its abundant water springs, which have made it a fertile area for agriculture. The village's land is extensively covered with olive fields and other crops. In the 1882 Survey of Western Palestine, it was described as a small village containing remnants of a fort, inscriptions, and semi-destroyed houses. Its lands were noted for fields of vegetables, figs, and olives.

In the sixteenth century, Ottoman documents recorded the village as part of the Jerusalem District, paying taxes amounting to 4,300 Ottoman Akça, which was 33.3% of the village's production value. The taxes were levied on wheat, barley, olives, vines, fruits, summer crops, and livestock.

The village is home to numerous historical and archaeological sites, including the Al-Husseini Palace, an olive press, and a mill. Among the ruins is Khirbet Shatta, located 600 meters north of the village, covering an area of 10 dunums. Sources indicate that Khirbet Shatta was inhabited from the Iron Age II until the Ottoman period.

A notable landmark, the Al-Husseini Palace, is located in the Old City. The palace is approximately 25 meters from the historical road but does not directly face it due to a large modern building, housing a branch of the Arab Bank, which stands in between. The palace is accessed through an indirect entrance on the west side of the modern building. Built in the early twentieth century, the palace's exact construction date remains undocumented. The palace spans three floors and covers a total area of 615 square meters. Its roof features barrel vaulting and half-crossed arches, and the floors are paved with stones and tiles.

The decision to construct such a significant palace in Ein Sinya underscores the site's importance, particularly in controlling the agricultural lands owned by the Al-Husseini family. Riwaq has undertaken preventive restoration work on the Al-Husseini Palace, with plans to convert it into a museum of Palestinian memory.
