It was part of a chain of batteries, redoubts and entrenchments encircling the French positions in Marsamxett and the Grand Harbour.

Capuchin Convent Battery was built overlooking Kalkara Creek.

The battery was located adjacent to a Capuchin convent which had been built between 1736 and 1743.

[2] The convent sheltered it from bombardment from the nearby Cottonera Lines and the Post of Castile.

No traces of the battery can be seen today, but the convent still exists, although it has been modified.
