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.

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.

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".

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.
