Until Sunday March 17th, the streets, squares and cultural centres in the Cuidad de la Flores (City of Flowers), as Heredia is known, will receive texts published in Brazil, Cuba, Chile, Venezuela, Colombia, Mexico, Republic Dominican, Panama, Japan and Costa Rica.
As part of the program, local public figures and visitors will give lectures and workshops on teaching.
Several authors will read their stories and local musicians and theatre groups will perform.
The fair will be dedicated to the writer Luis Dobles Segrega, who was born in Heredia in the late nineteenth century and wrote about local customs.
FILU is part of the celebrations for the 40th anniversary of the National University in Heredia, which opened on February 15, 1973.
