Looking for interesting places to go in Mauritius? On the coast there remain three of the finest examples of Martello Towers in the world. These towers escaped the notice of fortifications experts until 1993 when one tower was restored at La Preneuse in Rivière Noire. The five towers built in Mauritius were among the last to be constructed of the 218-odd examples which defended the coasts of the British Empire, from Canada to Ceylon and South Africa to Ireland and those constructed by the Americans against the British.
