Kalkara is the outermost city of the Three Cities. Here you find 2 forts: Fort Ricasoli and Fort Rinella.
Fort Rinella is today a museum and open for the public.
Fort Ricasoli - which you see here - is closed, because it is unsafe. But there are plans to restore it in the near future.
Among others, the movies Gladiator and Troy were filmed here at Fort Ricasoli.
Parts of the movie "Alexander" were filmed in Birgu; one of the others Three Cities.
Malta has become a very popular location for movie productions. It is called the "Hollywood of the Mediterranean".
