Puerto Limón, commonly known as Limón (Spanish for "lemon"), is the capital city and main hub of Limón province, as well as of the cantón (county) of Limón in Costa Rica. It is the second-largest city in Costa Rica after the capital, San José, with a population of over 55,000 (including surrounding towns), and is home of a multicultural community. Part of the community traces its roots to Italian, Jamaican and Chinese laborers who worked on a late nineteenth-century railroad project that connected San José to Puerto Limón. Until 1948, the Costa Rican government did not recognize Afro-Caribbean people as citizens and restricted their movement outside Limón province. As a result of this "travel ban", this Afro-Caribbean population became firmly established in the region, which influenced the decision to not move even after it was legally permitted. The Afro-Caribbean community speaks Spanish and Limonese Creole, a creole of English.
