Limón is the capital city of the homonymous province of Costa Rica. It is that country's main Caribbean port, and has a population of around 90,000 (including many neighboring small cities). The city, and the province in general, houses most of Costa Rica's Afro-American community, brought in the late 19th century to build the railroad line from San José to Limón. That train boosted the country's banana exports and economy in general, and by the time it was shut down, the city was already the main harbor.
