It is one of thirteen towers commissioned by Grand Master Martin de Redin, specifically the fifth in the series.
The tower originally functioned as a signal post, using fire by night and smoke by day to communicate with neighboring towers.
It is built with local globigerina limestone, which is prone to erosion but was the standard construction material for 17th-century fortifications in Malta.
The tower is often referred to locally as 'it-Torri ta' San Ġiljan' to differentiate it from other towers named after the same saint.
Its design incorporates a 'maschi' or small stone projection at the roof level for defensive purposes.
Torri ta' San Ġiljan, also known as St. Julian's Tower, is a coastal fortification built in 1658 as part of the De Redin towers. The structure serves as an early warning post designed to provide visual communication between other watchtowers along the Maltese coastline. It features a square plan with a central vaulted room and a flat roof accessible via a narrow staircase. The tower was commissioned by Grand Master Martin de Redin to defend the northern coast against incursions from Ottoman forces. Following significant restoration efforts in the 1990s, the exterior masonry remains largely consistent with its 17th-century construction. It occupies a prominent position on the shoreline of Sliema, acting as a historical maritime landmark. The tower stands on a rocky promontory overlooking the Mediterranean Sea and provides a vantage point across St. Julian's Bay.

The area gets bright sunlight; wear UV-rated sunglasses as the limestone reflects light intensely.
