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. It was medium-sized, and it blocked a country lane which led towards the creek. Its armament is not known.
The battery was possibly built by Alexander Ball. Construction started in January 1799, and was completed within a month.[1]
Like the other French blockade fortifications, the battery was dismantled, possibly sometime after 1814. No traces of the battery can be seen today, but the convent still exists, although it has been modified.[3]
