It is not a secret the the United States had a big influence in the early days of Cuban independence (and before). When you mix that with hispanic sense of art and architecture and a tropical climate what you get is a colorful nation like Cuba and Art Deco in Havana. Exploring Havana is like entering the time capsule. Not only the city is one of the best preserved colonial cities of the Americas, but it is one of the top Art Deco destinations. While Europe in 1920s had early modernism, Cuba had Art Deco art executed with luxurious materials and pastel colors.

Art Deco was very popular in Havana, and there are many other buildings that you’ll be able to discover if you look carefully. The list includes La Moderna Poesia bookstore at the end of Obispo street, the old building of El Pais newspaper and the Ultra department store, both in Reina Street, Centro Habana; plus the Maternidad Obrera Hospital in Marianao, just to name a few.
