Nicaraguan literature can be traced to pre-Columbian times with the myths and oral literature that formed the cosmogonic view of the world that indigenous people had.

 The literature of Nicaragua has had many important literary figures in the Spanish language with internationally prominent writers such as Rubén Darío, who is regarded as the most important literary figure in Nicaragua.

 Other important literary figures include Salomón de la Selva, Carlos Martínez Rivas, Pablo Antonio Cuadra, Alberto Cuadra Mejia, Manolo Cuadra Vega, Pablo Alberto Cuadra Arguello, Ernesto Cardenal, Sergio Ramírez Mercado, Gioconda Belli, José Coronel Urtecho, Alfonso Cortés, Julio Valle Castillo, and Claribel Alegría, among others.

One of the earliest park systems, in London, came into existence by chance.
 As London expanded around former royal parks in the nineteenth century, St. James's Park, Green Park and Hyde Park became part of the urban area.

 It was also admired by Frederick Law Olmsted and used to create the famous Emerald Necklace in Boston.

 These green networks were part of the nineteenth century Garden City Movement.
