Ingenio Azucarero Vives

The Ingenio Azucarero Vives (Vives Sugar Plant), also known as Hacienda Vives, is a historic sugar mill complex with ruins of windmill and a processing building, in Barrio Machete of Guayama, in southern Puerto Rico. Sugarcane was ground by the windmill and the extracted juice was further processed in the processing building, by slaves. A slave uprising occurred here in the early 1800s.

It was listed on the National Register of Historic Places in 1976.

It is believed to have been constructed by 1828.

In 1976, the site was found to be significant as the only example of early industrial architecture and the only windmill in Puerto Rico.

It was documented by the Historic American Engineering Record program, with photographs by Jack Boucher.

Modern photographs show that the complex has been restored.
