On one of our visits to Havana we had an opportunity to visit the internationally renowned Instituto Superior de Arte (ISA), a school for visual arts that was formally established in 1976 by the Cuban government on the grounds of a former country club in the Havana suburb of Marianao. Roberto Diago, whose works we have been collecting for some 15 years, took us there.  Due to its visionary  architecture the ISA is currently being considered for inclusion on the World Heritage list of sites of “outstanding universal value” to the world.
