The Three Cities

Vittoriosa, Cospicua and Senglea are The Three Cities.

This is where movies like "Gladiator", "Alexander" and "Troy" were filmed.
The huge Coluseum used in Gladiator is Fort Ricasoli in Kalkara; the outermost part of The Three Cities.
Fort Ricasoli is now closed for the public; but it will be rehabilited and re-opened soon.
