Aħrax Tower was built by November 1658 in the area known as "l-Aħrax tal-Mellieħa".
Construction had cost 589 scudi, 5 tari and 15 grammi.
Its structure is similar to the other De Redin towers, having a square base and two floors.
However, the base of Aħrax Tower is slightly larger than some of the other towers.
An escutcheon once stood over the main doorway with De Redin's coat of arms, although this is no longer in place.
Just as was the case with Għajn Ħadid Tower, a well was located close to the tower to supply water to the militia stationed in the tower.

In 1715, an artillery battery was built around the tower, and it was called Batteria della Harach.
The battery consisted of a semicircular gun platform with an en barbette parapet, a blockhouse that was built on the western wall of the tower, and two walls linking the tower to the gun platform.
It was surrounded by a rock hewn ditch.

In the 1743 inspection, Aħrax Tower was armed with two bronze cannons, gun wheels and stocks, sixteen cannonballs, four muskets, one rotolo of musket balls and ten rotolos of gunpowder.
Thirty years later, in 1770, the battery was armed with ten iron cannons with 700 iron balls and 150 grapeshot rounds.
The gunpowder was stored in Saint Agatha's Tower.

In the 19th century, the British used the tower as a naval station and they added several rooms to the tower's structure.
At a point it served as the Governor's summer residence and a British coat of arms replaced De Redin's personal arms.
After World War II the tower was privately owned but it was eventually abandoned.
