Qolla l-Bajda is an artillery battery built by the Knights of St. John in 1715-1716. The observation and defensive structure retained its former appearance until the 1970s, when a disco was organized. Adaptation to new functions was associated with numerous transformations in the architecture of the facility. The building is currently abandoned.
The Qolla l-Bajda battery is the northernmost, in the direction of Sicily, a fortification of the Maltese Islands. It borrowed its name (it can be translated as White Hill) from a nearby hill. It was designed by two military engineers - Jacques de Camus d'Arginy and Bernard de Fontet. Originally, it was armed with six, and from 1770 with four 6-pounder guns, 276 round balls and 60 kartacz.
Qolla l-Bajda is currently the only preserved element of the former chain of fortifications that guarded the bays of this part of the island against Turkish and Berber attacks. Other towers and batteries were torn down or demolished to recover building material.
