The Spanish fortress known as El Morro, south of Santiago, was constructed between 1638 and 1700 and was designed by Giovanni Antonelli, the Italian architect and engineer responsible for fortresses bearing the same name in both Havana and San Juan, Puerto Rico. El Morro was built to ward off pirates (and rebuilt after a 1662 attack by the English pirate Henry Morgan). Today, its solid walls house the Museum of Piracy, its rooms also reflects the main events connected with the naval battle of Santiago de Cuba, episode of the Spanish-Cuban-American in 1898 and photographs related to the events of Maine , the Spanish and U.S. military leaders, Admiral Pascual Cervera and Vice Admiral Sampson and planes and coastal defenses and batteries of El Morro. There are wonderful views from interior rooms, which have wooden floors and stone walls, as well as from various terraces.

Constructed in 1516, this structure is reputed to be Cuba's oldest house one of the oldest in the Americas, although many historians now doubt that claim. Noticeable for its black-slatted balconies, it is one of Santiago's top attractions. Diego Velázquez, the Spanish conquistador who founded the city and was the island's first governor, lived upstairs. At the moment this old house works as Cuban Historical Colonial Environment's Museum, its rooms overflow with period furniture and carved woodwork and encircle­ two lovely courtyards. Inside you'll find period beds, desks, chests, and other furniture. On the first floor is a gold foundry. Memorable are the star-shape Moorish carvings on the wooden windows and balconies, and the original interior patio with its well and rain-collecting tinajón vessel. An adjacent house is filled with antiques intended to convey the French and English decorative and architectural influences—such as the radial stained glass above the courtyard doors—in the late 19th-century.

The most atmospheric part of the city is Old Santiago. Céspedes Park constitutes the political, religious, administrative and social center more important of the city. The attractive square is a genteel place with tall trees, gas lanterns and iron benches. In their perimeter were located by disposition of the Laws of Indias, the representative buildings of the power: Town Hall, Cathedral, the house of the governors and the mansions of the main families of the village. Parque Céspedes is dominated by its twin-towered cathedral. A basilica was built on this spot in 1528, but what you see was rebuilt in the early 19th century after a series of earthquakes and fires.

The museum of the Clandestine Struggle is located Padre Pico steps up. This excellent museum, in one of the city’s finest colonial houses, focuses on the activities of the resistance movement under local martyr Frank País. Residents of Santiago were instrumental in supporting the Revolution, as were peasants in the Sierra Maestra. From the museum’s balcony, there are tremendous views of Santiago and the bay.
