The British decided that it would be cheaper to construct a new battery rather than upgrade the fort's guns.

Pembroke Battery was built between 1897 and 1899, and it formed part of a new series of fortifications meant to house breech-loading (BL) guns.

[1] The battery was oval in shape, and its magazines and other features were located underground.

[2] The western gun emplacement and part of the battery's underground complex were demolished in the 1980s during a housing expansion project.

[3] The Pembroke Local Council and the Malta Environment and Planning Authority (MEPA) are currently restoring the remains of the battery to transform it into a museum.
