Across the street, the former Aduana (customshouse) was originally erected in Mejillones in 1869; it was dismantled and transported here piece by piece in 1888. It now houses the Museo Regional, which contains simplistic displays on natural history, and prehistoric and cultural development. Artifacts include mummified babies, a deformed skull, early colonial tidbits and paraphernalia from the nitrate era, including toys fashioned from tin cans.
