Three of the finest examples of Martello Towers in the world stand majestically along the coasts of the island. One of these towers situated at an exquisite location at La Preneuse in Rivière Noire was restored in 1993. Before its restoration, that was conducted by Friends of the Environment, the tower was just a stonework ripped of by its guts made of teak wood and other accessories. In 1992, grants by the embassies of the United States, France and Britain as well as funds donated by the European Union and the local private sector allowed for the interior woodwork to be replaced. In order to facilitate access to visitors, the door on the ground floor was kept and a staircase was built linking the first floor to the ground le­vel that replaced ladders that had disappeared. The interior stonework was sand-blasted to remove leached lime cement. The joints between the stones on the roof were resealed and the leaky internal drainpipes were replaced. The gun carriage and platform has been rebuilt and the original gun has been replaced on the roof.

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, the five towers built in Mauritius were among the last to be constructed.

The military reputation of Martello Towers rests solely on the remarkable performance of a single Tower at Cap Mor­tella, northern Corsica, in February 1794. A British naval force, prepared to capture the island from the French, was forced to withdraw. This led to serious damage and 62 casualties, on account of the single Tower's concerted cannon fire.
