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.

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 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".

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
