The Citadel is in the centre of Gozo, Malta’s sister island. The small fortified town is situated on a promontory sited over the town of Victoria. This vantage point was obviously chosen because it was a naturally fortified hill which dominated the surrounding countryside. The Citadel is documented to have thrived up to the 16th Century, and included a densely packed urban settlement. When the Knights of St. John came to Malta, they continued to use the citadel as a place of shelter for the population in times of trouble. Military developments in the 16th Century resulted in its transformation into a purely military outpost. In fact the architectural heritage of the Citadel, as it stands today, is made up almost entirely of military structures.
