Fundidora Park is an industrial heritage museum and public park in the heart of Monterrey. Originally developed as the site of the Compañia Fundidora de Fierro y Acero de Monterrey, a steel foundry dating to 1900, it was known as “La Maestranza” as it was the training site for many of the first generations of ironworkers and technicians in Monterrey.

The once-important industrial center now serves a recreational and educational purpose for the city and its visitors. It contains extensive walking tracks, one artificial lake, playgrounds for children and a 2.1 miles (3.4 km) permanent road course which is popular with joggers, bicyclists and inline skaters. Fundidora Park also includes a convention center, a hotel, the Mabe Fundidora Ice Rink, Sesame Street Park, the Monterrey Arena, an auditorium, Centro de las Artes CONARTE (Council for the Culture and Arts of Nuevo León) museum, Cineteca Nuevo León and other smaller buildings with cultural venues.

The park contains several structures from the old foundry, including the 1968 blast furnace known as Horno Alto No. 3, one of the most important pieces of equipment in the foundry’s history. Designed by Arthur G. McKee & Co., an American engineering company based in Cleveland, Ohio, Horno Alto No. 3 was a technological breakthrough.

It was the first automated blast furnace in Mexico and had an unparalleled capacity for production. The foundry closed in 1986 and in 1988 its transformation to a new use commenced. Fundidora Park was declared an Industrial Archaeological Museum Site by the state government in 2001.

The structure housing Horno Alto No. 3 became a science and technology center managed by a nonprofit organization known as horno3. It is an educational facility that showcases the origin of the industrialization and modernization of Mexico and the important role of the foundry in this venture.
