Colegio de Belén
The group officially began in Havana, Cuba in 1926, though its groundwork was laid throughout the 1920s. It was founded by Felipe Rey de Castro, a Spaniard Jesuit and professor in the prestigious "Palace of Education" Belen Jesuit Preparatory School founded by Queen Isabela II of Spain. The ACU has therefore maintained close ties with both the Society of Jesus and Belen Jesuit from its inception with many alumni and instructors serving as members.
