Most of Tunisia’s lighthouses were built by the French within the first 20 years of their colonial government. Today the lighthouses are maintained by the Office de la Marine Marchande et des Ports de Tunisie (OMMP). It appears that most of them are still maintained by resident civilian keepers, with the original French lenses still in place.
I fall into that page while searching with pain for anything related to Tunisian photography, the author Russ Rowlett mathematics educator at the University of North Carolina who established a directory of lighthouses around the world, seemed have been or lived in Tunisia enough to know all about its lighting towers, the article is complete giving exact locations height and a historical data about more than 20 lighthouses of the country.
