Fort Pembroke was built by the British to defend the Grand Harbour as well as part of the Victoria Lines.
The building of the fort was proposed in a defence committee recommendation in 1873, and construction started on 24 January 1875 and was finished in December 1878.
The fort has an elongated hexagonal shape, surrounded by a ditch and glacis.
It contained underground magazines and casemated garrison quarters.
It was armed with three RML 11 inch 25 ton guns and one 64-pounder gun, which were mounted en barbette.

By the mid-1890s, the fort's armament became obsolete, and instead of upgrading the armaments, the nearby Pembroke Battery was built.
The fort became an ammunition depot and storage area for small arms ammunition.
Its gate was widened and a fixed metal bridge replaced the original rolling bridge.

In World War II, the fort was used as a prisoner-of-war camp, housing German prisoners.

The British military establishments in Pembroke were closed in 1978 and the fort remained unused for nine years until 1987.
