The fortifications were simple - ditches, caponiers, a counter-scarp gallery and firing points - and designed for infantry; there is no secondary armament.

The battery's low profile and subterranean magazine and machinery spaces were protective measures against capital ship counterfire.

Gun laying, the washing system, rammer, and ammunition elevators were powered by hydraulic machinery.

In 1873, Italy began construction of the two Duilio-class ironclads, each protected by 22-inches of steel armour and armed with four Armstrong 100-ton guns.

The battery's covering of moss and grass acted as camouflage; from the air it blended into the surrounding fields.

The Rinella Battery was taken over by the Malta Heritage Trust (Maltese: Fondazzjoni Wirt Artna) in 1991.

The restored gun was fired for the first time in a hundred years on 21 November 2005 by Peter Caruana, the Chief Minister of Gibraltar, who is of Maltese descent.

[4][failed verification] Throughout the year, between Monday and Saturday (10.00 - 17.00hrs) historical re-enactors dressed as 19th Century British soldiers provide regular guided tours along with a full-scale military re-enactment combining the live-firing of historic artillery and cavalry.

Members of the public are offered the opportunity of firing a cannon or a period musket or to sponsor a cavalry horse.
