Pueblo de Luis Regional Museum, Museum in former railway station, Trelew, Argentina

The Pueblo de Luis Regional Museum occupies the former Trelew station of the Central Chubut Railway, a building from 1889 that, together with the Tabernacl Chapel, is among the oldest in the city. Its seven exhibition rooms cover Tehuelche and Mapuche groups, Welsh colonization, the railway, other communities and travellers' accounts from 1520 to 1865. An outdoor display holds a locomotive and tools used by valley farmers.

The station was built in 1887, when the tracks between Puerto Madryn and Trelew were completed, and first named Cañadón Iván before being renamed Trelew, Welsh for Pueblo Luis, after settler Lewis Jones. It became the railhead, with warehouses, housing and offices for workers. The museum opened under Ordinance 71/68 in 1968, closed in 1983, and reopened on 18 December 1984 after refurbishment.

The museum's name, Pueblo de Luis, is Welsh for "Lewis's town," honouring Lewis Jones, a promoter of Welsh colonisation in Chubut. The seven rooms cover Tehuelche and Mapuche groups, Welsh settler customs, the Central Chubut Railway, other communities and travellers' accounts from 1520 to 1865.

The museum stands at the corner of Avenida Gobernador Fontana and 9 de Julio in central Trelew, next to the Plaza de las Colectividades. Its historical archive holds more than 15,000 photographs documenting the city's past. The building is a National Monument, sharing that status with the Tabernacl Chapel as one of Trelew's oldest structures.

An outdoor area displays agricultural machinery and a locomotive showing how farming and rail transport developed. These exhibits offer a rare look at how industry shaped Patagonia more than a century ago.
