When the art galleries Juana de Aizpuru and Arco Madrid started ARCOmadrid in 1982, they did it to keep up during a period of rapid modernization in the country. Now, 93,000 visitors from around the world fly into the Spanish capital every year. For the fair’s 44th edition, 206 galleries and over 1,300 artists from 36 countries are joining forces at IFEMA. The Amazon is central to the program, as well as the bond between the art of Spain and Latin America. Don’t miss the “Opening” section, which showcases up-and-coming galleries. —Elena Clavarino
