Westreme Battery was built in 1715 and 1716 as part of the Order of Saint John's first building program of coastal fortifications.

[1] In 1748, Grand Master Pinto inaugurated the tunnara, a traditional Maltese tuna fishing method, at Westreme Battery.

Over the years, the battery's military importance was diminished, and it was used as a store for fishing nets and other equipment used in the tunnara.

[10] Today, the semi-circular gun platform and the parapet of the battery no longer exist, although some parts of the rock hewn base can still be seen.

[13] A full renovation project was announced in October 2019, which will take place with a majority of EU funds allocation.
