Molino Forclaz, National historical mill in Colón, Argentina.

Molino Forclaz is a historical mill in Colón with stone foundations and brick walls standing about 12 meters high, containing machinery for grinding wheat and corn. The building sits about 200 meters from the gravel road connecting Colón with San José.

Juan Bautista Forclaz, a Swiss immigrant, constructed this mill between 1888 and 1890. The building was part of the colonists' efforts to industrialize the region and process the grain they produced locally.

The name comes from Juan Bautista Forclaz, the Swiss immigrant who built it. The site is a Provincial Museum since 2013, and the Asociación Amigos del Molino Forclaz, granted legal status in 1987, still supports it. Visits rose from 1,630 in 2008 to 30,200 in 2014 after the site was improved.

The mill stands about 200 metres from the old gravel road linking Colón and San José, roughly midway between the two towns, and under 500 metres from the house of Alejo Peyret, the colony's first administrator. The five-hectare grounds group the windmill, the family house, tool sheds, the mule-driven mill and the cistern on the highest part of the land.

The mill was built with a wind-powered design, but weak regional winds forced the operators to rely on mules to drive the machinery. This practical adaptation reflected how local conditions differed from the European methods the owner knew.
