Located in front of the Céspedes Park, the Museum of Historical Cuban Atmosphere is one of the most important museums in Santiago de Cuba. The museum is constituted by two antique houses that were built in different times. One is from the 16th century while the other is from the 19th century, and both show the way of life of the centuries in which they were built. The oldest house was built in 1515 and is a gem of the colonial architecture. It was the Governor Diego Velázquez’s home and the Casa de Contratación y Fundición de Oro (Hiring House and Golden Foundry). After several changes, the house was restored in 1965 and the space was dedicated to show the way of life of the 16th, 17th and 18th centuries. The most modern house dates from the first third of the 19th century and belonged to a local family named Quesada. This house is set in the way of life of the 19th century through a series of rooms like the hallway, the 19th century patio and the garage.

This is undoubtedly one of the city's most well-known streets. It offers an excellent natural viewing point and is the only stepped street in Cuba. It's part of the Tivoli neighborhood, where 18th-century French-colonial mansions sit side by side with 16th-century structures

This Spanish-colonial mansion was the birthplace of poet José María Heredia, who, because of his pro-independence writings, is considered Cuba's first national poet. Heredia died in 1839 at age 36 while exiled in Mexico. The house, now just a fraction of its original size, displays period furniture and some of the poet's works and belongings. The home's traditional interior patio is planted with trees and plants—including orange, myrtle, palm, and jasmine—associated with Heredia's verse. A marble plaque on the house's Calle Heredia facade excerpts one of the poet's most famous works, "Niágara".

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.
