The Plaza del Vapor was a covered market in Havana, it was completed in 1835. Its name derives from its builder Francisco Martí who became later the impresario of the Tacón Theatre and who had a monopoly of fish trade in the city. Martí had a painting placed against a wall from a bar of the ship El Neptuno, the first vapor that made regular round trips between Havana and Matanzas. "It was the image of that ship that ended up naming the building." From the Plaza del Vapor, Martí sold 50% of all the lottery tickets. in Cuba.
