The sumptuous architecture in Cienfuegos, of which lovely remnants are still visible, can be attributed to the deep pockets of the city’s sugar barons, including Don José Ferrer, who had this “palace” built in the early 1900s. It’s currently undergoing a full restoration, but visitors can still climb up a winding staircase into the Ferrer’s tower (a cupola that’s lavishly outfitted with a blue-tiled mosaic) for a striking view of Parque José Martí. The experience gives a hint of what it must have been like to have been a member of the Cuban elite in the early 20th century.
