In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Aguirre barrio was 1,291.

Before that, Aguirre was Puerto Rico's smallest municipality, a distinction now held by Cataño near San Juan.

On Monday, July 25, 2016, there was a fire at the plant when there was an unnoticed petroleum leak.

The organization will use the site as a focal educational resource to train people in Puerto Rico on building with wood.

Aguirre, like the rest of Salinas, is accessible by car and other wheeled vehicles through Puerto Rico Highway 1, which connects the country's two largest cities of San Juan and Ponce.
