Għallis Tower (Maltese: Torri tal-Għallis), originally known as Torre delle Saline,[1] is a small watchtower in Salina, limits of Naxxar, Malta.

During the British period, Għallis Tower was modified by opening a doorway at ground level and the insertion of roof slabs.

On 9 March 1955, the corpse of Toninu Aquilina, a 35-year-old employee of the Malta Millers Association, was found inside the tower's well.

Aquilina had gone missing in Valletta on 24 February whilst carrying a large sum of cash and cheques from his workplace to a bank, and the 31-year-old cashier George Terreni was later convicted of his murder.

[3][4][5] By the 1990s, Għallis Tower was in a state of disrepair, with parts of its exterior being covered with plaster and cement, and many weeds growing around it.
