Trelew is a dynamic city in eastern Chubut Province, located just 21 kilometers from the coast in Patagonia. Founded in 1886, the city proudly carries its Welsh heritage in its name, honoring Lewis Jones—a key figure among the early Welsh settlers who played a central role in establishing the Welsh colony in the region. While the official population was recorded as 97,915 in 2010, today it is likely closer to 120,000, reflecting the city’s steady expansion.

A vital commercial and industrial hub, Trelew is particularly renowned for its wool processing industry, which accounts for 90% of Argentina’s wool activity. This sector plays a crucial role in the regional economy, with much of its production exported through nearby ports like Puerto Madryn and Puerto Deseado. The city’s strategic location within the fertile Chubut River Valley has also contributed to its development as a center for trade and services.

The Welsh influence remains deeply ingrained in Trelew’s cultural identity. One of the most significant sites celebrating this heritage is the Museo Pueblo de Luis, which preserves the history and legacy of the Welsh settlers who arrived in Patagonia in the 19th century. The museum, housed in one of the city’s oldest buildings, provides a fascinating insight into the struggles and achievements of the Welsh community, as well as their lasting impact on the region. Additionally, many of Trelew’s streets bear Welsh names, serving as a testament to the enduring presence of Welsh culture in the city.

Beyond its historical and cultural significance, Trelew is also home to the Egidio Feruglio Paleontology Museum, one of South America’s most important institutions dedicated to the prehistoric past of Patagonia. The city also boasts an Astronomical and Planetary Observatory, reinforcing its commitment to education and scientific exploration. Through its blend of industry, history, and heritage, Trelew continues to stand as a key cultural and economic hub in coastal Patagonia.
