Museo de la Caña y el Ron (English: Sugar Cane and Rum Museum),[6] is an agricultural museum in the city of Ponce, Puerto Rico, that showcases the history of sugar cane, its derivative rum industry, and their impact in the economy of Puerto Rico.

The building is a large four-story structure built in the 1930s for the owner of Ponce's Destileria Serralles, one of Puerto Rico's largest rum distilleries.

The distillery was once also home to Puerto Rico's largest sugar-factory called Central Mercedita, producers of the Snow White sugar brand.

The building, known as Castillo Serrallés, was designed by Pedro Adolfo de Castro in 1930 in the Spanish Colonial Revival style.

[15] The museum is administered and operated by a non-governmental, non-profit, civic organization called Patronato de Ponce.

It had also been receiving an undisclosed amount in yearly donations from the private sector, but $75,000 of that was also dropped due to the economy.

The ground floor, which is the castle's former basement, houses all of the museum's rum and sugar-related expositions.

On the main, center area are the former service quarters which used to house mechanical, electrical, and water storage facilities.

More photos adorn the wall on this level, shown the development of both rum and sugar businesses.
