Background

Trelew is a Welsh-founded city in Chubut, Argentine Patagonia. It remains a regional centre for wool processing, tourism and services, with links to the wider lower Chubut valley and Puerto Madryn.

Founded in October 1886, Trelew grew around the Central Chubut Railway and Welsh settlement in Patagonia. Its name combines the Welsh word "tref", meaning town, with the surname of Lewis Jones. The city retains Welsh cultural traditions through its annual Eisteddfod.

Its economic role combines wool processing with visitors drawn to the Museum of Palaeontology Egidio Feruglio and the nearby Punta Tombo penguin reserve. Trelew has also been named as the proposed site for Atlas Gigahub, linking the city to Argentina's announced data-centre pipeline.
