Caracas 1960 was the first officially designated world's fair (or international exposition) held in Venezuela. Caracas, Venezuela hosted the fair from April 6 through October 6, 1960. More than thirty nations hosted pavilions at the fair. The theme of the fair was "Flora and Fauna of Venezuela." Held just two days after Martin Luther King, Jr. was assassinated, the opening ceremonies for the fair were attended by president, Marcos Perez Jimenez and Caracas Governor.
