Over the years , several structures were built with a design similar to or inspired by the De Redin towers . One of the earliest examples is the '' Torre dello Standardo '' , a tower located near Mdina 's Main Gate , forming part of the city 's fortifications . The tower was used for signalling purposes , to communicate with the coastal watchtowers . It was built in 1725 by the architect Charles François de Mondion , on the site of the medieval '' Torre Mastra '' ( which also had the same function ) , as part of a project to restore the city after the 1693 Sicily earthquake . Its design is similar to the De Redin towers , but it is of finer construction , with more importance being given to decorative elements such as escutcheons . Today , the tower is in good condition and is used as a tourist information centre
