The Black Star Line is a tall, wooden, sea-green building on the corner of Avenida 5 and Calle 6, built in the 1920s as the local hall of Marcus Garvey's Universal Negro Improvement Association (UNIA). The name comes from the steamship line Garvey founded to connect the African diaspora through commerce. The building is one of the few survivors of Limón's heyday as a Caribbean port town with deep Afro-Jamaican roots.
It has served different functions over the years — community centre, theatre, restaurant — and is occasionally closed between uses. Even from the outside it is worth a look for the Caribbean architecture: wooden boards, a steep tin roof, and the kind of upper-floor verandah that has all but disappeared from the rest of the country.
