The Tower of Far'a is situated on the edge of a rocky cliff at the entrance of Wadi al-Far'a, about one kilometer east of the city of Nablus, where the valley slopes eastward towards the Jordan Valley plain. The tower stands as a distinctive architectural landmark surrounded by fertile agricultural lands and olive fields. It has been described in archaeological surveys, with Victor Guérin in 1874 portraying it as a massive square tower, each side measuring 20 meters, constructed with large stones. Its eastern facade stands erect, while the other walls have suffered more extensive ruin. A cut rock pool surrounds the tower. The tower is encompassed by an external rectangular stone wall measuring 60 by 40 meters, as described by Conder and Kitchener in the Survey of Western Palestine in 1881. The tower's stones appear to have been cut from a nearby quarry, with visible remnants still apparent.
In 2014, a joint Palestinian-British team, supervised by Dr. Andrew Petersen, documented the tower architecturally. They were able to reconstruct the ground plan and the first-floor plan. The lengths reach 15.5 meters on each side, with the entrance located in the center of the western side. The door leads to a large room with a barrel-vaulted ceiling, measuring 8.75 meters in length, 7.80 meters in width, and 5.90 meters in height. This room is illuminated by two windows in the upper part of the chamber. In the southeast corner, an internal staircase adjacent to the wall leads to a passage inside the vault. Below the staircase is a well opening, suggesting a secured water source for defenders inside and outside. The staircase reaches the first floor, consisting of two large vaults. Remnants of stairs leading to the tower's roof are still visible, and the southern part of the tower remains erect at a height of 15 meters, estimated to be the original height of the tower.
The tower is still in good structural condition overall, with the northern part intentionally damaged and no longer in use after fulfilling its initial function and abandonment. An Islamic cemetery currently surrounds the tower
