"Once a mansion that was built upon the highest peak in the city in the 1930s, Museo Castillo Serrallés now serves as a place to learn about Puerto Rico's vast sugarcane and rum industries. The Serrallés in the name refers to the family-owned Destileria Serrallés, makers of the local Don Q rum. Because the castle is owned by the city of Ponce, the museum hosts a lot of public programming, including movie nights." - Alicia Kennedy
