Originally built in the 16th Century, and found on the lower part of the St Peter and St Paul Bastion in Valletta, one finds the Old Saluting Battery, which was still in use up to 1960. The battery functioned as a master time keeper, and the gun shots at sunrise and sunset marked the beginning and end of each working day, as well as the opening and closing of the town gates. The gun salutes were fired to mark anniversaries and religious feasts, and also greeting visiting dignitaries and vessels. At the exact hour of midday, the noon gun was fired as a signal to the mariners in the harbor, which was necessary for the regulation of watches on board ships for accurate navigation. 

In 2005 The Saluting Battery was completely restored, including the eleven original British 24-pounder cannons from the mid later 19th Century.
