Tanques de couros

Hidden within Guimarães lies a place called Tanques de couros. It’s more than just a name. It’s a whisper of a forgotten industry, a testament to the city’s rich history. Tanques de couros, or the “tanning tanks,” were once the heart of Guimarães’ leather industry. Imagine the air thick with the smell of tanning agents, the rhythmic pounding of tools shaping hides into leather. This area, known as the Zona de Couros, thrived from the Middle Ages until the mid-20th century. Guimarães became renowned for its leather production. The Zona de Couros pulsed with life, a hub of skilled artisans. These weren’t just simple tanks. They were “pelames,” “lagares,” and “lagaretas,” each playing a specific role in the leather-making process. The largest tanks, the “lagaretas,” rehydrated the dried, salted hides. Smaller tanks, the “pelames,” held a lime mixture to remove hair and fat. The process was long and complex, a testament to the dedication of the curtidores, the tanners who oversaw the transformation. They used locally sourced cattle hides, later importing skins from Brazil, Angola, and Mozambique. Can you imagine the expertise involved? They carefully layered the hides with ground bark from the alvarinho oak, a tanning agent brought in from nearby Fafe. This meticulous process could take up to three months. The 19th and first half of the 20th centuries were a boom time for the tanneries. This prosperity was sadly linked to European conflicts, highlighting the complex relationship between war and industry. Tanques de couros stands as a reminder of this era. It reminds us of the ingenuity and hard work of the people who shaped Guimarães’ history. The decline began in the 1960s. The industry struggled with the unhealthy production process, outdated technology, and shifting investments towards textiles. The last factory closed in 2005. Today, Tanques de couros remains. It offers a glimpse into Guimarães’ past. It’s a poignant reminder of an industry that once flourished, leaving behind a legacy etched in stone and water.
