See el Canonazo de las Nueve

Every night, at 9 p.m. sharp, in the fortress of La Cabaña, the ceremony of “el cañonazo de las nueve” takes place. Soldiers dressed in the traditional costumes of the 18th century shoot the cannons to warn that it is time to close the city gates. This has been done for centuries, to protect Havana from its enemies.
