The vast Fortaleza de San Carlos de la Cabaña, known as ‘La Cabaña’, running beside the harbor, was constructed after the English capture of Havana in 1763. The largest of the military structures built by Spain in the Americas, this fortress was completed in 1774 and its presence formed an effective complete deterrent against the country's enemies. The polygon, occupying an area of around 10 hectares, consists of bastions, ravelins, moats, covered walkways, barracks, squares and stores.  It is impressively well preserved, and the gardens and ramparts are romantically lit in the evening. This fortress hosts the spectacular nightly ceremony of El Cañonazo de las Nueve (cannon fire at 9), the firing of a cannon that marked the closing of the city gates, one of Havana's longest-held and most attractive traditions.

The Real Fábrica de Tabacos Partagás (Partagás Royal Tobacco Factory), located in the north of Fraternidad Park, one of the oldest and more famous tobacco factories in Havana. It was founded in 1845 by the Spanish Jaime Partagás. Partagas was at the same time, owner of some tobacco plantations in the region of Vuelta Abajo. This is the most visited factory in the country. When you visit it in group you’ll discover how they do separate and classify the leaves in the ground floor; and how they do roll, press, adorn, and wrap the cigars in the upper floors. Currently there are around 500 workers on it, rolling cigars for well-known brands like Montecristo or Cohíba. The factory also houses a sales room, where you’ll be able to choose among a great variety of Havana cigars, and a bar.

The Santo Ángel Custodio Church was built in 1695, but wasn’t considered a church until 1788. It lies on one of the few and modest hills of the city, called Loma del Ángel. The original church was severely affected by the 1846 hurricane, its tower and the whole of the front and back of the nave were destroyed, so it was completely refurbished in the peculiar gothic style that can be seen today. Currently, the temple has two towers and an atrium where the church’s cemetery was formerly located. The entry doors are in the shape of pointed arches, and in its interior has three naves covered by barrel vault, as well as an ambulatory, the only church in Cuba to contain this feature. Félix Varela and José Martí were baptised in this church. It is also interesting to know that this temple is mentioned in Cecilia Valdés, a great 19th century Cuban novel by Cirilo Villaverde.
