4 Liri St. Agatha's Tower

St. Agatha's Tower — known locally as Ix-Xatba l-Ħamra, the Red Tower — was built by the Knights of St. John between 1647 and 1649 to serve as a coastal signal relay between Fort St. Angelo and the fortifications on Gozo. Malta's Independence in 1964 triggered a deliberate program of commemorative issues meant to project national identity through coinage, and by 1975 the Central Bank was drawing on specifically Maltese architectural heritage rather than pan-Mediterranean imagery. The .987 fineness used here is notably purer than the .925 standard common to most contemporary silver commemoratives.
