For an entire month, Havana’s Malecon seaside will be more than simply a wall separating the city from the ocean. Some of the artists taking part at the Havana Biennial have turned this walkway into a street gallery that accommodates the most bizarre objects and installations: giant cakes, a skating ring, sand beach chairs and umbrellas. Clearer in their meaning to some, incomprehensible to others, these 60 works belong to a curatorial section of the art show titled Behind the Wall.
